Currently unplayable, jumping is stupidly difficult and there are many areas that you commonly clip outside the map or slide around for no reason (I made it to the vents before I got stuck in the void outside them).
HOWEVER, this is just version 0.1. I really love the idea of the game, so I'm definitly going to come back here every now and then to check for new versions.
Although, if you think the game is cool, download it anyway, maybe you'll fair better than me or find more specific bugs that'll help development even more!
