Interesting game. Didn't mind the grid based movement, however, you need to tweak how much the player is looking down. Kept on wanting to look up. I would make it controllable by the player, the ability to look forward, down or even up. Was a bit lost as to what to do. I know I triggered something, made some progress walking past inactive enemies, then tried to go through an unblocked corridor but couldn't for some reason. Then an enemy approached -- that I didn't even know was an enemy -- and I died. Still, I think it could make for an interesting action-puzzle game that is first-person with grid-based movement. Perhaps with the player able to interact with things with LMB instead of just having to walk over things.
