Would be great if you could better distinguish the available upgrades (e.g. 1/2) from the finished ones. The buildings part does come a bit early while I'm still "overwhelmed" with the starter mechanics. The game is addictive and the "one more round" feeling is well implemented.
Not sure when a mine starts over and also not sure what the arrow icon means in the mine.
I build the buildings but didn't realize I had to dig tunnels to make them operational.
Thank you so much for your detailed reply and your feedback, those are some great suggestions! Complexity considers various letters, so "jjj" would have a lower complexity as "asf". e.g. "fall" gives 15 coins while "fals" gives 20.
