Okay 12#.
Art: 10/10 It fits the style.
Music: 8/10 - This is way too simple the music, I doubt anyone will like this loop music.
Gameplay: 9/10 - Pretty easy at first but as you progress more it's harder which is challenging and requires you to dodge way faster. You get buffs during the waves which is pretty useful.
Overall: 9/10 - You did a good job on it. But how does this fit the theme if you don't know the story behind this?
