Ok, loved the fact that it has achievements, I'll do anything for a game to give me achievements so I made it all the way to the end. The music and the art really created a good feel. If I had access to some automation elements, I'd dig to the center of the earth with this.

I too ran into the UI bug where scroll down broke, but I eventually got it to work.

Nice work!

Nice game! I love the art, plus the achievements are pretty cool :)

That was a good time. I got to the point where I wasn't able to select any new upgrades. The UI button to scroll down broke on me. Other then that you guys got a solid game .  I would be scared to yell the tittle of this game in the hood.  XD.

I love the art style and the music! Really love that retro sound.

Gameplay wise it could be improved, as other comments  said, the upgrade pricing seems to jump too fast, and some idle progression would be nice and interesting to implement with the theme of the game.

Also I found a "bug",  if you don't purchase your upgrades in order you may get stuck with a low upgrade for a while until you can get a better one  (I bought the golden shovel first and then the silver one, and I had to dig with the silver one until I was able to upgrade again.) Maybe making the upgrades additive instead of enabling the last tool you purchased or something would fix that.

Also, I need to know the name of the dude, he seems really cool. He looks like a close relative of Barry Steakfries (From Jetpack Joyride)

Edit: wtf the coment was sent 3 times, I deleted the other 2

I love the concept and the art style of this game!
For me, the upgrade pricing feels a little too quick. From 50 to 250 is a lot without an auto clicker

I am the digger clicker! 
The only thing that's missing is more idle progression, maybe a little digging helper, or an automated drill.
