Good job! :D
I think the game has nice aesthetics and I really like the variation in the enemies and obstacles. The game feels polished with nice particle effects and sound effects.
When I was at the last level I died, and I had to move back to the start, which felt a bit bad. I think if you want the game to still be challenging you could decrease the health slightly and have check point after each curage you collect. But apart from that I think you did a good job.
