That's a coal story bro!
The visuals are great and the art looks polished, and you have put a lot of thought into creating a really cool atmosphere and a likable protagonist. The game input is a bit weird, you can move left and right with A and D but can't jump with W. It took me a while to realize that you should play with the arrow keys. The instructions were unskippable. With a bit of polish this is a game that I can easily myself playing in my free time.
Good job!
