Been playing this game and it's fun. You have to build up all these conveyor belts and mining machines and smelters so that you've got this entirely automated factory that you gotta keep running. You also have to fight aliens and try to work out the pipeline as you expand the factory but still try to keep it efficient.
It's got a Linux demo you can play free, but I pledged and got access to the beta which has given me new levels with more features.
It's a really cool game, check it out and pledge if you can!
