Thank you! There were a lot of requests for some label system to be implemented, so if I continue the game I'm planning to add investigative tools and item features on the back of the cards similar to flash cards. One consideration was adding a scoring system where you get exactly enough money to buy items at their max price, so you're score would be however much you manage to save. Maybe the money you save could add up between rounds and you could use the money to buy tools.
There were a couple people that mentioned the educational aspect, which ended up being a happy accident. A mix of anatomy and botany I guess.
