My computer fixed itself (I don't know how) so I managed to sneak some time on the game today, working on the side-area you can explore when you get to 2-8-5. There are minecarts moving around on rails, presumably once used to carry minerals from somewhere to somewhere else. This is a mine tileset, after all.
Since I don't really know how to make good sprites, I just take what I have in my sprite pack and modify them. The minecart for instance is a weight flipped upside down with greyscaled logs as wheels!
Currently working on: Continuing the story
Time spent on the project so far: 201 hours
