How to play
- Run and you grow: every second of running is +1 size. Bigger is also faster, and faster jumps farther.
- Big smashes walls and jumps wide gaps. Small fits thin beams and low tunnels. Watch the size gauge at the bottom.
- Cyan pads and the checkpoint dial shrink you. Orange boost rings give +6 at once.
- Walk gently (or hold Shift) to move without growing, so you stay small for a beam ahead.
- A slip puts you back at the checkpoint with the size you had there. Beat par with no slips for 3 stars.
- Try the Daily Obby: five new stages a day for everyone, with a rule of the day.
Controls
- Phone or tablet: Drag on the left half to run (a small push walks), drag on the right half to look, tap Jump, ↩ for the checkpoint.
- Keyboard: W A S D or arrows to run, Space jump, Shift walk, Q E turn the camera, R checkpoint, Esc pause.
- Mouse: Drag to turn the camera, the wheel zooms.
- Gamepad: Left stick to run, A to jump, bumpers to turn the camera, Y for the checkpoint.
Tips
- Too big for the beam ahead? Stand on the checkpoint dial for a moment: you shrink 12 sizes a second.
- Walk (Shift, or a gentle push of the stick) to cross a long tunnel or beam without growing past its size.
- A gap sign says the size that clears it. Run a little longer before the jump if your number is short.
- Gold walls are shortcuts. After a rebirth you start big enough to smash some of them.
About this game
An obby where your speed and your size are the same number. Every second you run you get +1: a little faster and a little bigger. Faster jumps farther, and bigger smashes brick walls. But a thin beam gives way under a big body, and a low tunnel stops a giant at the mouth. So every section asks one question: how big do you want to be here?

Twelve stages in four neon zones (Circuit, Candy, Ice and Sky) each tell a size story. Grow on a long runway to clear a wide gap, step on a cyan shrink pad to cross a beam, smash a wall marked 14, then squeeze through a tunnel. Pick the small line or the big line at a fork. Ride ferries, run over crumbling tiles, dodge spinning bars, and hit orange boost rings for +6 at once before the big jump. A gauge at the bottom always shows the size the next obstacle wants, and a see-through outline of your body turns green or red before a beam or a tunnel.
Slips are part of the fun: you pop back to the last checkpoint with the size you had there, in under a second, and the clock keeps going. Beat par with no slips for three stars.
Play a Run of all twelve stages with your size carried over, replay any stage, or try the Daily Obby: five new stages every day, the same for everyone, with a rule of the day like Heavy, Tiny or Wall Rush. After Home Tower you can rebirth: start bigger, earn a new trail and body shapes, and score more.
