This is a very fun game, it's unique and I haven't experienced the lack of knowledge with any other game thus far. However, there is a frustrating bug I've noticed where the angel octopus thing's leg-tentacles will clip through walls and kill me. I don't know if that's a problem in the regular version, I play exploration mode, but I figured it'd be a good idea to say something in case it could be fixed.
edit: WASD controls seem to be swapped half the time? W moves you backwards sometimes, D moves you to the left, and vice versa with A and S.
