I have 25 super humans, but I'm not seeing anything about "The Mind". Is that not in the game yet?
"Subject Automation" Upgrade seems a bit too expensive compared to the rest of the curve of the game. But it doesn't take a ton of time to get there. Perhaps the few upgrades prior to it should scale up in cost a little bit so that this one feels more natural as well.
I suggest that unassigned Humans and Super Humans are added to tab text. Something like this:
The reason I suggest that is that personally I constantly forget to assign my regular humans and since they are hidden way back there it's sometimes a really long time before i figure it out. But maybe when the numbers get big this might make the tab look ugly. So maybe just an asterisk or something when there were unassigned humans/superhumans.
Just my suggestion.
