This was really nice to look at. The visuals and the music match perfectly. I'm always a sucker for dynamic music and this was a great implementation of it, I had the upgrade where you'd deal bonus damage if you are under 33% hp but I wanted to hear all the music so never made use of it.
While playing the character does feel quite floaty, and this can make it very annoying to pick up resources dropped by the enemies. I think some pickup radius would be very helpful with this.
All in all, a very fun and polished experience!
