I'm approaching late-game stats. (Roughly 5 GTi, have built one of everything that's available to build, etc.)
I don't know how best to proceed. I can keep mining iridium & uranium & osmium, and using the results to build gizmos to create heat, pressure, O2, etc... but the game doesn't give me suggestions as to what to do. It was doing that earlier in the game, but no longer.
Once I get the ability to plant trees, I'll do that, but now that I have the super-duper energy plant, I really don't know what to focus on.
