A nice Candy Box type game. The graphics are simple, but clean, which is nice.

WASD controls would have matched a lot better with the mouse. Nice at first but gets a bit boring quickly.

Fun game :)
I liked the sense of exploration in caves, but I found it more rewardig to regenerate them to find iron rather than dig blindly. This would probably not have been an issue if there was an easier way to gather than having to click to confirm though.

I also liked the world variety in my playthrough, but got stuck on world #5 with a 100x100 empty grid.

Good job. Mined a lot of stone. Not sure I can handle the search for gold, but I enjoyed it

Thanks all for the response :D

Ohems: sorry for the little bit inconvenience, I tried to make each level unique

Ikr: what do you mean with "regenerate them"?

It was easier to exit and enter the cave again to find iron, than to dig in the walls. When I entered after exiting, there'd usually be two visible iron nodes in the starting room walls.

Oh, yes, but I think I should just keep it, or is that change acceptable?

I thought digging and exploring the cave was a fun gameplay mechanic, so ideally I'd like to find iron that way. But when I can dig 20-30 tiles without finding any iron, it's just more efficient to exit and enter again to instantly find it.
My suggestion is therefore to increase the chance to find iron when digging a little bit :)

Is it allowed to update the game now?

Great innovation!

Nice feel to it...

Thanks :D
