Okay, it took a lot of time, but I managed to understand how to produce stuff!
A lot of people said it, and I agree, this game really needs either a tutorial, or better icons: at first, I thought the compressor thing to make iron gears was a drill to extract metal ^^
Although, the conveyor belt and furnace were easy to read, and the color palette is nice, the game still has some good visuals here and there.
Apart from that issue, for a 48h game, it works and it is fun to try to organize everything for the growing factory, granted you really have to figure out the machinery first. ^^'
Not a bad job at all! =)
