This is a neat concept for a forgery game. However, the first two weeks are very repetitive. Once you manage to get the last four binary numbers it's easy sailing until day 21 imo. it all comes down to there until then is whether or not the shop themselves will have any swap or reverse card you can customize to easily profit $5 for each card. Once the colors started changing everyday then it becomes more strategic, but the randomness does slightly hinder that since if it takes multiple move (usually just two) you have to go into the negative and got to hope that tomorrow color is close and the shop has multiple swap or reverse cards. I think this could be a really great puzzle game, but I don't think the randomness of the shop fits it well. Maybe it might fit better in a level based game where you're given set cards to choose from to get the appropriate forge.
