Very cool! The art was good, I liked how all of the enemies acted differently, but were still challenging, I liked the different abilities, I liked the start menu, and I liked the beginning cutscene.
The character did go faster diagonally, which means that you need to normalize the inputs in the movement code. Also, when I pressed the button to go back to the menu after I died, the music played, but the menu didn't load.
Overall a fun game. Good job!
