About Blastronaut

Blastronaut runs entirely in your browser: click play and you're in, with nothing to install and nothing to sign up for. It keeps its rules small and its challenge honest, which is a rarer combination than it should be.

It's played with keyboard and mouse, so there's no setup beyond your hands and the screen. Desktop, laptop, phone: the game doesn't care, it just loads and runs. Hit the fullscreen button and the browser gets out of the way entirely. It's the kind of game you open to test and close an hour later.
