I for one am a big fan of mazes, so I enjoyed this game! I think the corruption mechanic is really unique and has a lot of potential if you wanted to expand upon the game after the jam.
I think an interesting mechanic would be for the monsters to move at the same time and speed as the player, making it almost puzzle like, but at the same time that would negate the monsters speeding towards the player when you get close, which was something I really liked. Regardless, good work!
