Solid game, simple and effective!
I think my biggest suggestion might be to implement the score somewhere on the screen while playing, or maybe some kind of combo meter. It'd be nice to know how well I'm doing, especially since everyone else is posting their scores lol (plus number go up feel good)
It might also be worth trying to increase the difficulty over time to the point it becomes impossible, like how some old arcade and puzzle games go faster and faster until they're unplayable. I noticed there was a difficulty ramp but it seemed to plateau fairly quickly and I didn't feel like I was being challenged beyond that.
I thiiiiink there may be a bug after a while, because at some point you have to wait years between drops... My final score was 415 but that was more because I quit after waiting around too long than skill issue.
I think the idea was very cute, and the iconography complimented it nicely. In terms of aesthetic the only thing I think would help is maybe music?
Overall nice entry!
