This Is the Only Level Studio Online — One-Key Platformer

This Is the Only Level Studio Online

A browser remake of the joke-that-becomes-a-game: you only move left and right, and each time you clear a level it secretly changes one rule — gravity, your size, the controls, even who moves.

Ten levels, each altering exactly one thing from the one before.

Controls: left/right arrows or A/D. Up to jump once the game hands you a jump. Tap the left or right half of the screen on touch.
