Very nice game! Great artstyle and catchy music. Very original concept for "enemy".
Although I have to say it is difficult, like some other person suggested it should have difficulty modes/settings and the current version would be second hardest or potentially hardest. And also maybe make the controls for shooting more clear and give different key binds for dash and shoot when a person uses WSAD to move (please make jumping with W possible).
Good job! Keep up the good work!
