Interesting take on the theme, and the spritework is quite charming. Nice minimalist entry :) if you guys want some suggestions, I think changing the mouse cursor when the mouse is over an interactable object is a great touch. Some tweens are also nice, but I'm suspicious to talk about them, since maybe I might even overuse them hahaha anyway, nice entry!
Oh, also, an online leaderboard is always a nice inclusion in my opinion. I usually use Silent Wolf, it's quite easy to setup. Hope you don't mind my suggestions!
