Well, it took me about thirty seconds to end up floating through space forever... not a great first impression. And when I managed to properly die after restarting the game just crashed...
As others have said the movement system is interesting but really really clunky and unfun in its current state. Both the mechanic itself and the level design need a lot of work to make the unorthodox movement feasible. The spacesuit also felt really inconsistent as to whether you would stick to walls or end up launching yourself the same way as if you weren't wearing it at all - it'd be a lot nicer to use if it consistently stuck you to walls and switching out of the spacesuit was required to launch yourself.
