I don't really understand how is the game related to the theme of the jam but get the coins is really satisfying. I want to get it all!!!
Well, the only game to upgrade, or PROGRESS, is by failing to get all the coins. Also, to finish the game you have to buy something in the shop, so the only way to "win" is to lose :D
Oh, I see, I didn't get it. :)
Also, I can become addicted to coin pick up. hahaha
