Loving this game. It's a factory simulation thing where you have to build up ever more complex coloured shapes. I was never sure about these types of games - never played Satisfactory or Factorio - but this was cheap as chips so the perfect opportunity to try. Now I might get one of the others.
I think you can grab a demo from the Factorio website.
You'll know if it's for you based on that before spending anymoney
