The art is certainly a highlight here. :D
I think the game has a good mechanical core as well, but I did have to figure it out more or less fully by intuition and trial and error.
The main critique I would offer this game is that the player receives little feedback concerning their actions and enemy actions, and that makes it harder to understand the mechanics generically. It's a cool battler game, just needs a bit more polish for its true form to come through. I hope you keep developing this game :D
