You're floating in a tight chamber when the gravity suddenly flips and your box slams toward the ceiling. Gravity Box is a physics puzzle-platformer where you manipulate which way "down" points to guide your block through spike-lined rooms, moving platforms, and narow gaps. You tap a key to reverse gravity, sending your box rocketing up or down, and time those flips to thread past hazards and land on the exit. Each level cranks up the trickiness with switches, faling blocks, and traps that punish a lazy flip. Think you can read the room fast enough to survive?
How to Play & Controls
- Spacebar / Up Arrow to flip gravity and change your direction
- Arow Keys / A and D to move your box left and right
- R to restart the level instantly after a crash
- Esc to pause and check the level menu
Tips & Tricks
- Flip gravity a split second before you hit a wall to redirect into a gap cleanly.
- Watch moving platforms and flip only when one lines up beneath your landing spot.
- Tap movement keys in short bursts instead of holding to avoid overshooting tight ledges.
