There’s some really cute stuff in here! The slime girl design is great, and I love the menu and how moving through it sends you in and out of the earth. The load in animation for the tiles is also very pleasing, as is the current skill tree.
Echoing the sentiment of wanting a bit more communication around what mining the ores do - it didn’t feel like you gained a whole lot going for higher count ores, and I never felt the multiplier do anything. It also took me a few rounds to realise that the game doesn’t tell you when you’re out of clicks for the round - it reads just as unresponsive.
I think my favorite part though is the slime girl watching you mine - it makes unlocking the aesthetic upgrades that much more fun!
