Wow, you hated Gleba so much you went back in time a year to stop playing factory games?! (Space Age came out just under a year ago)

I loved Gleba because it makes you rethink how you build a factory to avoid stockpiling and storage and instead keep everything moving. If you're struggling with it you can also just use bots a lot and it works pretty well. If you're struggling with the enemies you just need to defend your pollution cloud and they basically don't attack at all.
