I like the idea of this game, and this short prototype leaves you with a lot of room to add features. Adding some puzzle features like collectables, enemies, keys, and whatnot would help to spice the gameplay up a bit. I did notice that occasionally switching directions results in a weird curve-like motion instead of a smooth movement into the next direction, which does result in some moments of frustration in trying to move around the maze. Overall though, I liked this submission and feel there's a lot of unexplored room to explore. Good job! :)
