Was fun, but getting the secret upgrade (whatever it is) is a pain! I get around a 100-150 money before I run out of oxygen, and I got to about 600 gems before I gave up. It's a fun game loop, but I wish the expedition was a bit faster paced.
Understood, thank you very much for the feedback. Balance in games is hard, and I’m a terrible game designer on top of that :D
