I really liked the idea. I think there are very few games about trading in the market—usually trading is just a side mechanic in games. However, for a game like this, I believe you need to prepare a really well-crafted set of instructions. It took me more than 5 minutes to fully understand the game :D Maybe I’m getting old, I don’t know, but this is just a humble suggestion. I’m not sure if it’s allowed, but I think you should update the instruction page. Congratulations on the submission.
