Slime is a physics toy built around one idea: your character is a soft, sticky blob. Pull back to stretch it like a catapult and release to launch, then let it splat, wobble and cling to whatever it lands on. The levels are climbs — the goal is up, and the route is whatever surfaces you can stick to on the way.
It plays a bit like a gentler Getting Over It: there's no punishment for a bad launch beyond falling back to a ledge you already passed, and the satisfaction is in the wobble as much as in the progress.
Click and drag backwards, like pulling a catapult, then release to launch in the opposite direction. Pull distance sets the power.
It is fiddly rather than punishing — falling costs progress but never ends the game, so it suits a patient session more than a quick one.
Yes — drag and release with a finger. It runs in the browser with nothing to install.
