beautiful pixel art work, it must have taken a lot of man power to properly make attack animations in a 2d format and it works really well.

the semi rouge like system is interesting with each upgrade also coming with a downside, however some of the abilities are a bit overpowered.

the grade system is an interesting to add replay value.

one negative point is that some sound effects feel missing, however overall a very enjoyable experience. thank you for posting this :3
