I really like the aesthetic of the game, the art is amazing. The movement is great, the character moves just the way you want it too, and the feedbakc is satisfying when attacking. It's cool that the last boss uses the abilities of the other bosses as the Head Honcho, and the exchange mechanic is simple and well implemented, their life for an upgrade! Really fun game overall.
If I could add something, it would be some way to check the CD of your dash/ability, I just used my dash/abilityhoping I had them. Other than that, nice game!
