Yeah, I did have pretty much the entire world mapped out before this though, just not the player path(s).
Meaning, where are you supposed to go first (a bit of this was mapped out), what upgrades block this area or what else do you need to get through there etc.
This made creating rooms harder because I didn't really know exactly what upgrades the player should have in those rooms.
So hopefully this will now speed up this process.
And yes, the feeling like no progress is being made even though I do a hundred things has been a problem for a while.
Hopefully this helps with that as well. :)
