Nice animations idea. Getting damage looks excelent. BUT... Graphic side is not quite right. All the sprites all different types and sizes. Example:
Main menu (Hight quality, Vector, Rounded, No outline):
Player (Pixel art, One color outline):
You see what i mean. All the sprites "should" be at least same type if not size. But I do understand that 3 hours are 3 hours. After all i had nice time playing the game. :)
