Very fun game, I really like that when you hit a enemy the game freezes for a bit it makes the whole thing smooth and satisfying.
The background song wasn't really fitting with this game and a bit repetitive but it was a good song overall.
The game looks awesome but I would add a particle effect that plays when a enemy is killed.
You should also add more things and add more variety.
Very good game overall
(Tried to be the more sincere possible)
