Visuals and sound design are great, maybe it's a bug but the background music just randomly stopped after a while. Also, the font might need a bit of tweaking, it was kind of difficult to read at times. The balance is a bit off I think it becomes too easy after a few turns, especially after you get to the shop for the first time and have enough coins you can just clear boards constantly. That's a relatively small issue though, overall such a good idea and execution.
