And then Super Humans are a slog. Can only get one at a time and most of the upgrades only do anything for Humans (where you don't need help). Literally just the one that gives you more of its own currency and the next one have any use at all. You slog through the whole game again only to be rewarded with x2 to that upgrade, then 1.5x, then 1.25x, etc. Both humans and super humans should have some re-balancing.
