Really fun puzzle game! It's all about counting out your steps and trying to follow the rules of the game. The limitation was added in really well, as an enemy's presence can ultimately decide if it was the right approach to the room or not.
Controls: Not that they're bad, but when I tried to use WASD I was thrown through a bit of a loop.
But ultimately really fun, and I could see you making a really difficult series of puzzles with this concept! You get 2 additional cookies.
