Gravity Jumper
Flip gravity to run on the floor or ceiling, dodging gaps and blocks and drifting through low-gravity zones.
Jump Over is an auto-runner built around variable jump height: a quick tap gives a low hop and holding the button gives a full jump. Crates and logs demand height, while hovering drones punish jumping higher than you need.
Keyboard: Space / ↑ / W to jump · P pause · R restart
| Action | Keyboard | Touch / mouse |
|---|---|---|
| Jump | Space, ↑ or W | Tap the game or the JUMP button (mouse click works too) |
| Start / play again | Space or Enter | Start Game button |
| Pause / resume | P or Esc | Pause button above the game |
| Restart | R (after a run or while paused) | Restart button above the game |
The game pauses automatically if you switch tabs. Sound effects are generated in your browser and can be muted with the speaker button.
Your runner moves on its own. The only decision is how long to hold the button.
Run as far as you can. The score counts distance traveled, so it climbs continuously and faster as the run speeds up. The Speed readout next to the score starts at 100% and rises to 213%.
A single collision with any obstacle, on the ground or in the air, ends the run.

Jump Over is rated Easy: it is a single-button game with a small set of obstacle types, and each run starts slowly. It ramps up in two ways. Running speed rises at a steady rate from the first second until it has more than doubled (the Speed readout goes from 100% to 213% after about 38 seconds). Separately, the random extra space between obstacles shrinks as your score grows, reaching its tightest spacing around 6,000 points, although a minimum gap that grows with your speed always remains.

Jump spike strips, raised blocks and crushing spike blocks, with checkpoint flags and three lives.
Tap and release the jump input quickly. Releasing while you're still rising cuts the jump short, and holding it gives a full-height jump.
Drones hover at a height a full jump reaches, but a short hop passes underneath. When a drone sits above a crate, a short hop is the way through.
Score is based purely on distance traveled. Because the run speeds up over time, points arrive faster the longer you survive.
