Under the Red Sky

Under the Red Sky is a fast 3D parkour game where you race through more than 70 obstacle-filled levels using running, jumping, climbing, bouncing, and wall-running. Instead of giving every stage one fixed solution, the game encourages you to find faster routes and improve your previous completion time.

The part that changed my runs most was learning not to follow the most obvious route automatically. A path that looks straightforward can be slower than a short wall-run or carefully timed jump. Once you start looking at each level as a small movement puzzle, the game becomes much more interesting.

How Under the Red Sky Works

Every level has the same broad goal:

reach the finish as quickly as possible.

How you get there is much less fixed.

You can run directly through a section, climb around an obstacle, bounce from surfaces, use wall-running, or find a route that is not immediately obvious.

That freedom is one of the game’s biggest strengths.

The official description specifically encourages players to find different routes or create their own way through a level.

Under the Red Sky Controls

The browser controls are intentionally small:

• WASD: Move
• Arrow Keys: Alternative movement
• Spacebar: Jump

Those simple controls support most of the game’s advanced movement.

You do not need a long list of separate keys for every parkour action.

Instead, movement depends on your direction, momentum, timing, and how you approach nearby surfaces.

For technical background, the MDN KeyboardEvent documentation explains how browser applications read keyboard actions such as movement and jump inputs.

Speed Comes From Momentum

Moving quickly is not just about holding forward.

Your speed depends heavily on how smoothly you connect actions.

A clean jump into another movement can preserve momentum.

A badly timed landing can slow the whole run down.

The biggest mistake I made was treating every obstacle as a separate challenge.

The better approach is asking:

Where should this movement leave me for the next one?

That turns isolated jumps into a continuous route.

Wall Running Opens Faster Routes

Wall-running is one of the mechanics that separates Under the Red Sky from a simple jumping platformer.

Some areas can be completed by staying on the obvious ground route.

Others become much faster when you use nearby walls.

I found it useful to look at walls as part of the course rather than as boundaries.

If a surface runs alongside the direction you need to travel, it may be there for a reason.

That said, using a wall is only helpful if it actually improves the route.

Adding unnecessary movement can make a run slower.

Climbing Gives You Another Option

Not every route is based on horizontal speed.

Some levels use vertical movement heavily.

Climbing can help you reach platforms or connect sections that initially look separated.

The useful habit is looking upward before assuming that the only route continues straight ahead.

A higher platform may create a cleaner path through the rest of the stage.

More Than 70 Browser Levels

The current browser version contains 70+ levels.

Speedrun.com currently tracks 77 individual levels for the game, which provides another useful view of how substantial the browser version has become.

That level count matters because the game does not rely on one endless course.

Each stage gives you a new movement problem.

Some emphasize:

• Jump timing
• Wall running
• Climbing
• Route selection
• Momentum
• Vertical movement

That variety keeps the same small control system from feeling repetitive.

Each Level Is A Route Puzzle

The fastest route is not always the easiest one.

You may find a safe route on the first attempt that gets you to the finish reliably.

Later, you might notice a platform or wall that lets you remove several seconds.

That gives Under the Red Sky two natural stages of play.

First:

Can I finish the level?

Then:

Can I finish it faster?

I would learn a stage using the safer route first.

Once the layout makes sense, start experimenting.

Look Before You Jump

Speedrunning creates pressure to move immediately.

That can actually make the first few attempts slower.

If a level gives you a moment to see several possible platforms, use it.

A second spent understanding the route can save much more time than repeatedly failing an unnecessary jump.

Once you know the level, that pause disappears naturally because the route is already familiar.

Bouncing Can Preserve Flow

Some sections use bouncing movement to connect platforms or change direction.

The important part is anticipating where the bounce will send you.

Do not wait until you are already airborne to decide what comes next.

Before making contact, look toward the next useful landing area.

That makes the bounce part of a planned sequence rather than something you simply react to.

Route Experimentation Is Rewarded

There is no reason to assume the intended-looking route is always the fastest.

The game is specifically designed around finding alternative routes.

One run might use stairs.

Another might use a nearby wall.

A third might combine a jump and climb to skip part of the normal path.

This is where repeated attempts become useful.

You are not only trying to perform the same route more cleanly.

You are also testing whether a better route exists.

Personal Best Times Give Levels Replay Value

Under the Red Sky encourages you to beat your own previous time.

That gives completed stages a reason to stay relevant.

I would not chase perfect times immediately.

First finish the level consistently.

Then identify the slowest section.

Improve that one part.

A small improvement in several sections usually produces a better result than trying to play the whole stage recklessly.

The Game Has A Speedrunning Community

Under the Red Sky has dedicated speedrun leaderboards.

Speedrun.com currently tracks full-game categories as well as individual level times.

This is useful because it confirms that route optimization is not just a side activity.

It is a major part of how experienced players approach the game.

Developer Federico Calchera has also stated publicly that the Poki browser version is the official version used for browser speedruns.

The Official Browser Version Matters

Federico Calchera specifically stated that the official browser version of Under the Red Sky is hosted on Poki and warned that versions appearing elsewhere were not authorized for official speedrun submissions.

That is worth knowing because browser games are frequently copied across unrelated websites.

For accurate game behavior, updates, and speedrun rules, the official build is the safer reference.

Desktop, Phone And Tablet Support

The current browser version supports:

• Desktop
• Phone
• Tablet

That support is confirmed on the official game listing.

Desktop uses keyboard movement.

Mobile versions adapt movement and jumping to touch input.

The W3C Pointer Events specification explains how modern browsers support different pointing and touch devices through a shared web input model.

The level structure remains the same.

The main difference is how comfortable you feel making quick directional changes.

Desktop Works Well For Precise Movement

Keyboard controls make desktop a natural fit for speed-focused play.

WASD and arrow keys both work, so you can use whichever layout feels familiar.

I would pick one and stay with it.

Switching control styles while trying to improve a personal best only adds another variable.

The biggest gains usually come from cleaner route execution, not changing the key layout.

The Steam Version Is Much Larger

Under the Red Sky also has a standalone Steam version.

Steam lists Dedra Games and Federico Calchera as developers, JumpButton Studio as publisher, and records an Early Access release on February 18, 2026.

The Steam version currently includes:

• More than 80 trials
• Single-player
• Multiplayer
• Cross-platform multiplayer
• Steam achievements
• Steam Workshop
• Level editor support

That makes it a more expanded version than the original browser release.

Browser Version Vs Steam Version

The browser edition is the easiest way to understand the core movement.

It gives you the parkour levels, route experimentation, and time-based progression without requiring installation.

The Steam version expands the idea much further.

It adds additional content, multiplayer systems, achievements, workshop support, and a level editor.

So the better option depends on what you want.

If you mainly want quick parkour stages, the browser edition is enough.

If you want the larger evolving version, the Steam release has much more structure.

Multiplayer Exists In The Expanded Version

The current Steam edition officially supports:

• Multiplayer
• Cross-platform multiplayer

That is confirmed directly by Steam.

The browser game’s main description, however, remains focused primarily on completing levels and improving times.

For accuracy, I would therefore avoid presenting every browser session as live multiplayer.

The expanded standalone version is where multiplayer support is clearly documented.

More Than 80 Trials On Steam

The Steam description says Z-Corp has built over 80 Trials.

This is slightly different from the browser version’s 70+ level description.

That difference is expected because the standalone version has continued expanding beyond the original browser release.

It also supports additional environments and content.

The developer plans to continue improving the Early Access build before its full release.

Early Access Is Still Developing

As of September 2026, the Steam version remains in Early Access.

The developers currently say they are targeting a full release around October 24, 2026.

They also state that Early Access is being used to collect player feedback and improve different game modes and ways to play.

That means features and content can still change.

For a game page, I would keep the Early Access status clearly separated from the more established browser version.

Who Created Under the Red Sky?

Under the Red Sky was created by Dedra Games and Federico Calchera.

The browser listing uses the credit:

Dedra Games × Federico.

Other games associated with Dedra Games include:

• OvO Classic
• OvO Dimensions
• Quivershot
• Fantasy Merger
• Disco Droids

Several of these use much smaller-scale platform or action systems, while Under the Red Sky expands heavily into 3D parkour and speedrunning.

Under the Red Sky And OvO

Players familiar with OvO may recognize the same interest in movement and route efficiency.

OvO uses compact 2D platforming.

Under the Red Sky transfers that focus into a 3D environment with:

• Wall-running
• Climbing
• Vertical routes
• Multiple paths
• More freedom in how a level is completed

That makes Under the Red Sky feel more open while still rewarding precise movement.

Browser Release And Update History

The current official browser listing records:

Release: November 2024
Latest update: September 2026

Earlier records indicate the project was already playable during 2024, with some databases recording an August 2024 release window.

The safest way to present the current platform history is therefore:

Official current platform release: November 2024
Latest verified platform update: September 2026

For the standalone edition:

Steam Early Access release: February 18, 2026.

Current Under the Red Sky Rating

The current official browser listing shows approximately:

4.4 from more than 467,000 votes.

This can continue changing as more players vote.

It is best treated as a current platform snapshot rather than a permanent game statistic.

Common Under the Red Sky Mistakes

The first mistake is always following the most obvious path.

The second is trying to move fast before understanding the level.

Another mistake is treating every jump separately instead of planning where the landing should lead.

It is also easy to overuse wall-running simply because it feels faster.

A wall route only helps when it actually reduces distance or preserves momentum.

The final mistake is restarting an entire strategy because one jump went badly.

Often, only one section needs changing.

A Better Way To Improve Your Time

I would improve a level in four stages.

First, finish it.

Second, learn the layout.

Third, identify the slowest part.

Fourth, experiment with one alternative route.

This makes improvement easy to measure.

If the new path saves time, keep it.

If not, return to the reliable route.

Once several small improvements are combined, your personal best can drop significantly without needing reckless movement.

Related Categories

Under the Red Sky fits naturally into:

• Parkour Games
• Platform Games
• 3D Games
• Running Games
• Skill Games
• Speedrunning Games
• Action Games
• Movement Games

The current browser platform primarily classifies it under Platform Games and also associates it with parkour, running, action, skill, and 3D categories.

What Makes Under the Red Sky Different?

Under the Red Sky gives you a finish line without insisting on one correct route.

That changes the way levels are played.

At first, you are simply trying to survive the jumps.

Then you begin noticing walls.

Shortcuts.

Higher platforms.

Different landing angles.

The same level gradually becomes a route-planning challenge.

That is what gives the game strong replay value.

The controls stay almost identical from the first level onward.

What improves is your understanding of movement.
