Hi! You've made a neat game, it's fun to play a stealth-oriented roguelike every once in a while :-)
There was a real sense of suspense at times, as if I was actually hiding around a corner while being hunted. I also liked the ending quite a bit although I did accidentally skip past the very last screen.
By the way, I think I may have found an exploit? If you walk straight into a guard that is tracking you, you can trade positions with them a few times until you eventually subdue them. It seems repeatable although I don't think it works if another guard sees you both.
I also ran into some odd situations at times. I think one is expected where a guard will just watch the stairs or a corridor without moving. But the really odd one is on the pink level below, where the three guards with "no vision" are just standing there not moving. I noticed similar affects near the single-tile walls, I wander if it messes up their pathing? Or maybe it's working as intended... figured I'd let you know either way.
Anyways I enjoyed the game, thanks for making it :-)
