I cleared out the whole mine and bought all (But one) upgrades. I don't know if this is intentional, I'm bugged, or an oversight. I ended up being about 3000 emeralds short of buying the final(?) upgrade.
Obviously very fun otherwise or I wouldn't have spent 15 minuets at 10:30 at night on it. I would love to see more content or games from you in general!
