Thanks for your reply. Helpful, except for No. 1. The question is if anybody has encountered something related to low stats (worth mentioning regarding lewd events) and not what it means, that's indeed made known by the game. I don't see any impact so far.
The only thing I've seen with low stats is you won't sleep if you're about to piss yourself, and you'll stop/won't start streaming if anything bottoms out. Bottoming out on rest or hunger gives you a willpower check, and then you get shipped to the clinic where you can restore those needs, and then get charged a bunch when you leave.
Bottomed out release gives you a small arousal minimum, that also seems to serve no purpose.
The only stats I see that serve any purpose are rest and hygiene. There's at least 1 scene you can get while you sleep regarding your room mate, and it's when you unlock inclinations. There's also a couple scenes that involve you going to the showers. Every other stat just exists for its own sake.
Temporary bars like pain, satisfaction, and humiliation only exist to raise/lower bars they're attached to. Arousal's only function seems to be when you climax, although there's at least one mini scene you can get by posting a code to a remote toy, wearing it around, and climaxing in public. Drunkenness can allow for certain options you'd otherwise need higher disinhibition to get, but capping it causes no issues, nor does there appear to be any consideration once you leave the area where you can get drunk.
Stats in this game are very disappointing imo, and just make the game way grindier than necessary. The developer says the intention is to funnel you into scenes, but for the vast majority of scenes I can recall, they just don't. Almost all scenes are either skill related, or completely independant and just rely on you showing up from other prompts, like your best friend telling you about the college parties. There's quite a few scenes that come from skill development, but the only thing stats serve there is to make that take even longer, and then they have the decision to put hard caps on skill gain for a day.
