awesome game! i do really think that mouse based controls in general are pretty underused and i think it's super cool that you deviated from the norm with this. the control scheme is challenging but not too punishing, and it kept me wanting to keep playing to get a higher score. although the art clashes pretty harshly with itself as each thing is in a different style, it's easy to overlook because it maintains that feeling of arcade-y fun.
also not to self promo too hard here but i also tried to get creative with mouse controls in my game, consider checking it out!
