I feel like there should be a point in the game where you can exchange gold for gems. But the exchange is a quarter or half of what the in-game shop says. I feel like this could be a way to get more monsters, and to also free all the monster in the main story section of the game. This could also be a gem exchange, or if that's to overpowered, maybe a gold for food exchange. But that is also a quarter or half of what you can get by growing it normally. Even though I feel like this could go nowhere and probably most people have already said stuff about this I generally feel this could be a great thing to add. Thanks for Reading.
