Really love the art style and enemy/character designs here. The animations are also generally solid overall, and I especially liked the enemies'! I do wish deflecting wasn't tied to the dodging/spinning mechanic, because it made it difficult to actually deflect things. If I deflected while moving forwards, I'd spin into a horde of enemies; but if I deflected while moving backwards, I just moved away from the projectile without deflecting it.
More SFX would also be helpful for things like hearing where enemies are coming from, when a projectile is about to be shot, etc.
The game also started getting pretty laggy for me once a lot of enemies started spawning in at once (around 225 kills for me). It might be nice to have a wave based system instead of having them constantly spawning all the time.
Overall, fun experience!
