The 8 computers puzzle is optional, what was the last thing you did? (turn on fans, get an upgrade, etc.)
the last thing i did was go thru the edge again where i got the brick and either the luna dial or the sun thing, i don't remember.
From the edge you go to upper engines and shift the barricades. If you did that, you should be able to enter lower engines from the entrance in city to progress further. No need to worry about items outside of star matter, they’re just collectables
thank you !
