It took me a while to figure out how to dig an which blocks are actually destructable. After that it was pretty straightforward. Good game.

I'm not sure about the game. Good try though.

Not very bad graphics. It hasa a gameplay mechanics for a digging game.

digging didn't work for me :( Looked like a fun game tho! Graphics are pretty neat ^^

Took me a bit to understand the game but when I dit it was actually really fun. Perhaps add a tutorial and a hint that you have to go right to get to the mine where you can dig.
The sprites are ok but sadly inconsitent in resolution. The indestructable blocks in the mines are a great addition and also increase the difficulty a bit after further down. Forced me to think more about what blocks i mine so i can reach the gold. That was really nice. The Upgrades are nice and good paced in my opinion. But still the gameplay gets repetitive after some time.
One thing I would change is the constant clicking. Thats annoying. Perhaps let the player hold the mouse button to mine.
I hope my feedback helps. Cheers.

Fits the theme, relatively nice graphics, however you really want to add some instructions, took me ages to understand that I have to go right to start mining and you have to click multiple times on a block to mine it, whereas the animation loops when you hold click. I'd say either remove the loop or make it possible to mine while holding the mouse button.
Otherwise the balance and pace are good.

As other said it lacks of a tutorial to get what things do what but in general it is a good digging game, the music was good aswell as the sound design, good job, well done!

I'd honestly disagree with comments before me saying that the game is any hard or hard to know what to do. I just read description and went right kinda hard for me to find it any hard xd. The clicking was not that much of a problem ( i have 3x click mouse ) but i get that with 1 click it would be frustrating. Game was fun to me tho! It had simple mechanic and simple progression simple graphics which IMO for LD is a good thing because we're not supposed to make AAA games. I liked it! GJ!

Cool little game. I would have liked to have some feedback about the "destruction level" of the blocks. At the beginning I thought I wasn't able to dig. Good work overall!

Hm, I like the game. Graphics, controls, gameplay, audio. Everthing is fine, but I don't understand how to move/use the coal wagon, so when I miss to dig "stairsways" to get up again I have to close the game and have to begin anew.
