Party Punch (Rhythm game)

Hello, i have been working on a rhythm game for a while, and i want to share what i have right now . I really will appreciate feedback and criticism.

In the screenshot are the controls. It can be a little difficult at the beginning but when you practice a while you will score perfect, just follow the beats. I have a problem with the synchronization but is a work in progress.

RULES: hit the enemies with their respective color.
