Well I'm a sucker for anything music/beat based and this is scratching that itch.
I didn't really see a use for dodge and rest but I'm sure with more time you could build out the mechanics further.
Some ideas:
- Maybe there's a point system for the abilities (maybe a sound system ;) ). So you can't just spam the most powerful ones.
- Goals beyond enemy clearing. You could create so many different sound powers, so what other obstacles could you face?
Great work!
