I am glad you like it! I am currently working on the crafting system and on world persistence, so your game status will be saved, even if you close the game.
I also want to make mining rock a bit more interesting:
- add ability to get "cobblestone" from rocks
- add "mineral clusters" that become visible once you first hit a piece of rock, so you can decide for yourself if you wanna mine that rock
- some rocks might have special effects, e.g. it could collapse the the area in front of you and reveal a secret cave with treasures
