I think it has great potential bro! the only criticism I have is that there should be more types of cards in the first area, with more explanation on whats going on. I just found myself a bit confused with just text prompts feeling rushed and then just picking animals that I didn't quite understand.
Also, I did find one way to break the game:
If you choose an exibition and choose your workers, you can just hit the "back" button and reselect the exibition, and it will refresh your gold but keep your workers. I could even sell my workers back to stack up gold!
Again, I love what this is, those few things are the only things that kept me from craving more and more
