StarJump

Reach the star above the lunar tower.

A short, single-level platformer about finding your way up. Chain double jumps, dodge traps and collect six coins on the climb to the final star.

• One lunar tower with three checkpoints and a best-time challenge.
• Keyboard and touch controls, with layouts that adapt to portrait and landscape screens.
• Local progress: continue from a checkpoint in the same browser or app.

How to play

Move: A / D or ← / →
Jump: Space, W or ↑. Press again in the air for a double jump.
Pause: Esc or the on-screen pause button.
Touch: hold an arrow with one finger and tap jump with another.

Click Run game to start. The first browser load downloads the Python runtime and may take a little while. Fullscreen is recommended. The game interface is currently in Russian.

Android preview

Download StarJump-Android-preview.apk below for Android 8.0 or newer with an up-to-date Android System WebView. The game and runtime are bundled, so the APK can run offline.

This is a debug-signed test preview. Android and iPhone hardware testing is still pending; mobile feedback is welcome. iPhone players can use the browser version. The APK is for Android only.

From a graduation project to a new release

StarJump began as my college graduation project in 2024. This version revisits the original level with more efficient rendering and collision checks, consistent physics, responsive menus, touch controls, checkpoint saves and an offline Android build.
