Hello, I was amazed by the amount of effort you have placed into the game and can find near to no flaws at all. However, for improvements, I would suggest maybe adding up a "skip animation" button for when the exp is running or maybe a "refresh shop" button by paying money. Otherwise, it stands at the top5 of itch.io games I have played so far (I only played 5 and urs is at no.1 :))
