A fun little experience though I do wish the movement was locked to a 2d plane. Had a couple attempts where despite not moving with W or S the ruler would be slightly off from my position and I'd fall instead of landing on it lol otherwise a solid entry, great work!

There is no limit to how long the ruler can be, which makes the game incredibly easy.

Nice game! I like how we're just a tiny eraser hopping around stacks of books, and I enjoyed making the ruler as long as possible and skipping some stacks.
