something that doesn't help is that the game is honestly quite slow to get going....
it takes a lot of luck to get strong girls, resources to upgrade them seem to drain way too fast (if you get them), and like Pero Pero Seduction there's quite the paywall when it comes to gacha (cause pulls are few and far between).
also, who's bright idea was it to have a skip function for events, but not the main storyline.... you get infinite stam til rank 30 and increased exp til rank 50, but have to sit there clicking multiple times instead of that nice skip function the event has (but the event also doesn't give nearly as much EXP and it also drains stam).
hell, i even got my ass handed to me by level fucking 3 raid bosses.... why is low level ones so hard hitting?
