It looks quite nice but, it's not much of a game in my opinion. I decided to try comparing two games where one I tried to get the score as high as possible, and another where I simply left the game on to do its own thing. Somehow the latter game actually has a higher score than the former.
I'm really sorry to say while it does look pretty and I like the aesthetic, this doesn't really feels like a game to me, it feels like knocking on the glass in a goldfish bowl and the goldfish just respond randomly each time, sometimes not responding at all.
Edit: Right, I realized my comment was really unnecessary harsh and deprived of useful information, so just ignore all of it.
The problem lies with that randomness play too much of a part, but since it is the main mechanic, I really do not know what to tell you for improvement that doesn't complete changes the game...
It did fits the theme of the jam, but I would say the player shouldn't feel mostly random in their chances in a game
