Really cool idea, and well executed. I love the way you balance a sort of zen-like car-wash simulator with the frantic Undertale style bullet hell mechanics. Really cool. A nice art style and great SFX to compliment it as well. I sort of wish there was a little more washing before the battle sequences, the pacing between washing and battling felt maybe a little too focused on the combat, whereas I really enjoy the cleaning part, but it all was really great!
