Nice visuals! If you made these yourself, congrats very cool :-)
The game runs nicely and is pretty fluid. Actually quite a solid game.
The gameplay loop personally was a bit too slow paced for my tastes, having to eat a lot of cheese feels more like a task than a challenge. The enemies are a nice variation but they need to do something slightly more interesting. Somehow. Not sure.
In terms of level design: Level 3 is the hardest. The levels after that are relatively easy.
I managed to finish it though :-)
