pros: i really like the concept! i could see this working well as an idle clicker game with a bit of polish.

cons: the sprites are very simple, which can be a little confusing. i also don't understand what the 'play' room on the left is for? 

bugs: after buying the first powerup, the minecart is duplicated

The coin system is somewhat nice but I was not the biggest fan of the art it looks very misshapen and basic. But conceptually good

this look cool its  artstyle is abit basic and some the ideas you have are good but i couldnt progess to final bit im not sure if could fix that otherwise good job i give a 5/10

pros: the artstyle is really nice and it's easy to identify what everything is 

cons: i don't know what the room on the left was for

bugs: sometimes in the cave, the minecart would duplicate. 

Bug Report

the only real bug I could find was the mine cart would duplicate after getting the first upgrade, which I class this a class C bug.

I liked the sounds of when you get the points from the mine and you can get upgrades from the store, however I wasn't a fan of the target building on the left because I didn't know what it was for.

Good: I like the "idle clicker" style of game where you mine to get points and spend points to help get more points.

Bad: There's only one power-up to buy in the bank.

Bug: When you buy the upgrade and you go back to the mine, the animation for the cart leaving replays as you re-enter the mine. (Class C)

feedback

good: i like the concept of the game, it's pretty original and i like the sound design, it works well with the game,

bad: i'm not a fan of the pixel art, although i can tell what the sprites are which is a good thing, some of them seem a little unpolished.

bug report:

after the first go of mining it auto kicks you out even if you don't click anything. i'd say its inbetween a class C and a class B.

overall a decent game :)
