I enjoyed this one a lot! On the face of it, this game is super charming and has a nice, clean, simple visual style but the true value is in the gameplay, which goes out of its way to be unique and somehow manages to pull it off.
It drops you into several different combat mechanics, throwing and retrieving the coin on screen and running a coin shop where you gradually learn to spot the fake coins, something a little akin to papers please but with coin salesmen.
It got a little confusing and slightly overwhelming sometimes but if you go with it and learn the mechanics, it's smooth sailing. There is some real depth here, which is crazy given the time allowance and the rules of this jam.
Awesome job! If you ever make this into a full game, I'd love to play it more.
