Running and jumping. There isn't much else you do in this game - all you do is run and jump over pits and obstacles which require almost perfect timing. However the game is focused on that and has a great flow. The levels - very abstract in their nature - are quite hard from the beginning and you'll struggle to finish each one of them, let alone try to beat the scores. But the game puts you in some sort of trance where you want to repeat the level again and again until you manage to pass it. Also the music is very good and the strong point of this game's atmosphere (although personally i disabled the wireframe mode, i prefer the solids).

It is a nice game, although at five bucks it doesn't offer much. When i bought it it was a two bucks offer, which i think is more on the line of what it offers. Also it doesn't have any exploration whatsoever. I'm not sure what that was supposed to mean, but i never felt like i was exploring something. Also people who dislike jumping puzzles in general should probably avoid it or at least try the demo first. The game is an endless jumping puzzle. But don't be worried about that: it is an endless jumping puzzle *done right*.
