Super gorgeous game. Those mountains in the background are amazing!
I think the gameplay needed something to spice it up though, it got a little repetitive. I thought this would be like an incremental game where towards the ends you'll be breaking hundreds of ores a second, but it stayed more slow and introspective. Which is fine, just not my cup of tea, y'know?
Overall though, a very nicely polished game with a fun idea and beautiful art. Well done.
