Nice game! The pixel art was clean and the mechanic of where you went through different stages when you died was a cool way to take the tower defense genre! The animations were so fluid and expressive, great work there!
A few things that could be improved:
- Any tutorial at all would have been good to introduce the player to your game as I was quite confused on what the abilities on each of my forms was when I started
- Layering can be improved, like it looks strange how the knight can walk right over the crystal, makes it feel like the crystal/enemies is flat on the ground
- The enemies sometimes group up into this singularity blob where they instakill you if you get near them. Kinda makes it hard to comeback when enemies are grouped up on your crystal (but somehow I beat the game anyways even though I didn't kill the last wave of enemies)
Overall though great job! Fun game to play with a novel idea
