10/10 Great game! I just have a problem with the gem upgrades. It randomly switched on gem upgrades, and I didn't realize that it was on and I upgraded a stat, (I pretty much always use max so max was selected) and I lost a LOT of grinding of gems. Please add a confirmation screen for gem upgrades. Fantastic job otherwise. Keep it up!
