Game mechanics
- Spikes are instant death on any side. Land safely on top of blocks instead of on spikes.
- Blocks are solid: the top and floor are safe to land on, but their sides and the ceiling are deadly.
- Jump pads launch the cube upward with extra speed the instant you touch them.
- Gravity portals flip gravity for the rest of the level, so you fall toward the ceiling and run along it.
Autoplay
- Autoplay replays the verified solution that is guaranteed to finish the level without crashing.
- You can still press jump at any time to override Autoplay and play it yourself.
Levels
- There are five original levels with rising difficulty: Easy, Normal, Hard, Harder, and Insane.
- Your best progress and completion status for each level are saved in your browser.
Fullscreen
- Press F or the Fullscreen button to fill the screen (or the page area if the browser blocks it).
- Press Escape or the button again to exit fullscreen.
Tips
- The jump distance is constant, so timing is more important than jump height.
- Use the progress bar and your saved best percentage to learn where you usually crash.
- Watch for pads and gravity portals early — they change how you should jump after them.
