So far I went through 2 areas feet only. I love the soundtrack and how it dynamically changes. Love the monster bottles. I recon you should die after gulping 5 or more in a row xD. I wish there were more edibles. And waiting for enemies at doorframes is super powerful but to make feet only possible I guess it's the only way. One super cool thing about it, that's a bit like surprising stealth game is that you can actually see them coming over by the shadows on the floor and their sounds. Really neat.
There is a bug sometimes when you drink stuff too fast and the can appears on the left side of the screen, not in the hand, after which you cannot grab items.
