Obby Grow with every step

Start as a tiny cube, then watch your size explode with every platform you touch—can you survive an obstacle course that keeps changing your hitbox?

This isn't your typical obby where you just hop from block to block. Here, every step you take physically grows your character. Start as a puny little square, then after a few platforms you're towering over the course. At first it feels like a cheat code—bigger reach, higher jumps, easy clears. Then you try to squeeze through a gap you fit through five seconds ago and realize growth is a double-edged sword. I kept coming back because the difficulty curve is sneaky. Early on, you'll miss a jump and think it's because you're still too small. A minute later you're so big that the same jump overshoots into a spinner. The camera becomes your best friend: you need to constantly angle it to judge whether your current size can fit under that overhang or clear that gap. There's a real rhythm to it—grow a bit, reassess, adjust your timing. One run I got massive and thought I could just bulldoze through a narrow tunnel. I got stuck, wedged between two walls, and had to wait for the reset. Frustrating? Sure. But also hilarious. It's a simple premise that somehow stays engaging, probably because the growth mechanic forces you to re-learn the course every thirty seconds. If you like obbies that add a weird twist instead of just harder jumps, this one's worth a few rounds.

Don't rush the early platforms—each step counts toward your size, and missing one leaves you undersized for later jumps. Use the camera constantly. Your hitbox changes with every step, so seeing your feet and the next gap is half the battle. When you're significantly grown, start your jumps earlier than you normally would; momentum carries you further than you expect. If a jump seems impossible, loop back and touch a few more platforms to grow. Sometimes size is the answer. On mobile, drag to look at where you want to land before letting go of the movement joystick—it prevents overshooting. Moving hazards don't care how tall you are. Stay light on your feet even when you feel like a giant.
