UNDRAWN

UNDRAWN is a free HTML5 endless runner by DriftStudio. You're a doodle fleeing the B-2000 Eraser. When the page runs out of floor, hold the mouse to draw bridges and ramps — time slows while you draw and ink is limited. ~50KB, procedural audio/visuals, air flips, unlockable pens/pets, daily challenge, EN + PT-BR. Desktop + touch. AI-assisted development; original game by DriftStudio.

The premise is a doodle that came alive on the last page of a notebook, with an eraser hired to clean up. You run with A and D or the arrow keys, jump with space and jump again in the air to flip for extra height, fast fall with S, draw with the mouse or a finger and erase with a right click. Every stroke costs ink and every line crumbles after a moment, so the game is about spending the pen well. Three difficulty levels change how often checkpoint flags appear, with a hardcore mode that has none; there are three extra pens and four pets to unlock, five paper biomes from ruled notebook to blueprint, and a daily challenge that gives everyone the same page for a day. The whole thing is about 50 KB because every sound and image is generated by code. It is free in the browser on itch.io, with an optional $2.99 offline download.
