This is very very good, although I feel bad being killed by beaver! My only wish was not to restart all over again if I died at 2nd or 3rd stage.
Audio is extremely good, like every single UI movement have SFX and it makes it look super polished. I think so far you are the only one that makes spinner gives 3 attack. That makes the player divides the spinner into 3 section.
Not only that, the heal & block mechanic is pretty interesting twist!
