Really fun concept I liked the art, the sound effects, and the gameplay.
Having the different things you break have some different properties would be nice and would add some gameplay variety. Like maybe some need to be hit twice or have smaller hit areas but give more currency/time or something like that. I'd like it if I could keep playing after getting chonkier and there was some kind of change in gameplay when that happened. Being able to buy more time in the shop would be cool also.
Really good, especially for your first game!
