I thought the idea is really interesting. The variety between how each enemy controls and their abilities is not only fun, but a good way to keep the gameplay fresh. The biggest problem for me though are the controls. It would be much easier if you found a way to incorporate the abilities used on the mouse onto the keyboard like left mouse could be Z and right mouse could be X. The controls definitely lead to many deaths, and a another thing is that some checkpoints would be nice. Also, I really liked the art style. Overall, Good Job!
