I can see it's still in very early development but I think it's a good start for a mining game! It looks like you have already implemented random world generation which must have taken some time! There's not really anything to play right now but I hope development on the game goes well for you!

There isn't really a clear goal in that game, which I was kind of confused when playing. I didn't really know what else to do other than destroy the blocks in my path.

Not much here, but what you have is a decent start.
