I've been playing this game over and over for the past few days, trying out the different choices and the consequences they have, something I haven't really done for many games on this site. It's a really fun experience, it took me like, three days to figure out how to get the route I wanted through the current content.
The only real gripe I have with the game currently is that the stat checks seem a bit too high to pass unless you actively know about them. For example, if you try to help Sofia and Rio with their boxes on the first day, you basically need to have picked the Nerd stat bonus set (+5 int, +3 will) or it fails. This sort of lightens up once you have more freedom to play around with lights and get more stat boosts, but I've also noticed that the intelligence requirements for 'doing well' in classes are ridiculously high.
The first day of classes, the requirement seems to be around 5 int, which requires either a primary int boosting stat set, or a secondary and basically every single int boost you can get up to that point, and even then I'm not sure if that's enough, since I haven't mapped it out. By the second week you have to be around 8 or 9—my current playthrough had me around there and I still was seeing text for failing the check when it came to Professor Ward's third class. I suppose it doesn't really matter, but I feel like some ways of boosting stats quicker could be useful—either that or considering lowing the requirements on some of those checks.
Of course, I'm not the dev, and I have no idea what the real requirements are, or how much he's tweaked them, but it's something I've noticed a lot over the course of my own play. I'm probably wrong about all this, but I thought I'd offer my opinion on the topic, I guess. Still, I can't believe how many branching paths and consequences G28 has managed to fit into the game—for example, even though Monica doesn't have a bimbo 'route' tracker on her data, there's still continuity between her scenes—having her call the MC 'Daddy' in her second bimbo scene despite you being perfectly able to miss the context of it by not picking her first one.
And the orange lights—or, sleep spells, I guess—give you some nice extra tidbits of backstory on the characters. Learning about how Monica's mom sees herself through a major dream option, learning about Lydia's parents, getting an early look at Barberry's powers through Suzie, all of that is amazing. And I love that you can just stumble into faking membership in the coven with just one choice in the beginning of the game.
If I can gush more, I personally love Sofia and Rio—I like how driven Rio is, along with being a bit 'hard to get', and I'm a sucker for the impreg fetish, so you know I'm hitting that Sleep button on Sofia every time I see it. Jane is also pretty cute when you take the more romantic approach to her, as well. There aren't many characters in the game I really dislike, even. I think Kyle, Tom, Brittany, and Barberry are the only ones I've really got any reason to dislike, and all of those are pretty minor.
Though, well, I guess I do have one other very minor complaint. It feels weird having all of the mind shaping make you pick from the same exact list of 'mommy, brat daughter, or slave', at least to me, but I can see how making wildly different paths for each possible person you can mind control would be difficult. Again, it's a minor complaint, but I think that the mind reading parts of mental spells were cooler than the actual mind shaping, at least at the moment.
Just so I don't end the comment off on a bad note, I do want to ask a bit about corruption as a value. I haven't read through the whole thread, but I'm very curious about whether Corruption does or will do anything in the game—most people are probably going to end up taking the Succubus's deal, since it's one of the few ways to get up to using Dancing lights within the current content, and summoning the servant a few times for extra info. I do feel a bit strange using Corruption for anything else—the only other time I've used it is for healing Sofia, though I have checked out the time stop scenes and backed out of them like a coward. Maybe I'm just being too wary—I'm curious how other people in the thread have been using or not using Corruption, honestly.
