I loved this game. I found it challenging and a lot of fun! I needed help from a walkthrough to get through some of it when I got stumped, but got a lot of satisfaction from all the tricky parts I figured out on my own. As others have said, be prepared to die a LOT, but that's part of the fun of it! You never know what's around the corner, and it's exciting when you get through a tough section. I'm definitely going to play it again.

Purity and atmosphere. the sound design is perfect, the controls simple, and the puzzles are the right kind of maddening. i love that the game is greyscale! the deaths are frequent and gory, and you come to embrace them.

Beautiful game. simple and captivating atmosphere. good physics and a lot of fun. turn off the lights before you start the game.
