Toilet Roll is a physics game about unrolling toilet paper: you guide the roll along a course, and the paper trails behind — which is a genuinely awkward thing to manage around corners and obstacles.
It's silly and it works, because the paper behaves like real paper: it tears if you pull it wrong.
The paper trails behind you and behaves like real paper — sharp turns and obstacles tear it, so the roll has to be guided rather than driven.
Yes — a silly, harmless physics game.
Yes — drag to move. Nothing to install.
