The art style was amazing, and the game play was a lot of fun. It did loose my interest quite quickly since I played alone. I would have loved to see a way to find other people hosting in the game, on top of the room code system.
The smaller enemies had some pathfinding issues. Multiple mice got stuck on a jump pad, and one creature got stuck on an edge. The mines were also very unforgiving, hurting you even if you moved at top speed.
