only feedback is make the last 2 mine levels easier to get. there is no xp scaling
like for example i just quit because i dont want to have to waste 15 mins to get the last mine level without a singe upgracde
It's a demo, meaning it's most likely missing upgrades which would make getting levels more feasible.
Thanks for the feedback! We've pushed a balance fix that should make the late-game mine progression much smoother.
