Asteroid Factory

It's a nice Factorio clone without belts, in a pre-pre-alpha state, or let's say a development playground. You mine resources on different asteroids, every asteroid has one particular resource. You build local production chains on each asteroid, where you first have to supply your machines manually. For some products you have to fetch resources or products from other asteroids. Later the resources fly between machines on their own on a single asteroid (local logistics). For the research of higher tiers (currently there are only two tiers) you have to transport items between asteroids, but global logistics are not implemented. So in the end you find yourself continuously carrying products between asteroids. I played it for a few hours and it's ok for its current state. The dev has put a lot of work into it already, so you can imagine how much it costs to develop a full-blown factory game.
