I hope the game will become more difficult in the future update. The first time I tried it, it was quite complicated to manage the money between your personal expenses and the school in the beginning, especially without selling that hypnotic object to the detective. After that, the game is easy to corrupt people and get what you want, especially with quicksave before risking certain movements with the students. It would be interesting if you do an ironman mode, I can't control myself and I have abused quicksave a lot.
On the one hand, once you know just what to do it is pretty good to raise up reputation and get some good corruption in so I can understand making the game more difficult or present situations that ask whether you really want more money or something possibly useful like the mind control gun (even though said gun really is mostly useless since most people are in groups and once hypnosis is high enough you can control individuals easily enough).
On the other hand, it'd be great if penalties didn't hit nearly as hard later on in the game or if certain elements weren't as hard as they currently are. The fact that the Sex Shop owner is both a PTA member and also important to the Cabaret stuff while also having no quests of her own means the only way you can progress with her is either spamming hypnosis (which will likely be super low when you try to get the first stage of stuff and as such fail), or spam drugs (which seem to fail for a long time anyway and also gets expensive fast). Not to mention how hard some later events will wreck your reputation justifiably even if it still sucks all the same (one the students start doing exhibition stuff in the park you can never hang out there or you have a chance to lose a whopping 4+ rep gain, which there is no good way to earn 'that much' in any short amount of time).
I get that at least part of this is either planned on next release or any future release (not all quests are done and clubs will be looked into), but honestly it's not so much 'difficulty' I'd be looking forward to but more opportunities. After having played games like Village of Corruption with all the succubus conversions, it'd be neat if there were more places you could corrupt in some way or even if it does have to be "the hard way" like with the Sex Shop that you can still cause further corruption.
Like, imagine if you worked at the restaurant enough or corrupted the owner/staff enough that they started serving food with less clothes or even 'tainted' the food in some way and corrupted the town that way and because it's adults doing it you don't get pinned for any blame? You corrupt the Onsen and people start doing it in the baths more or they implement a 'no towel' policy. There's already precedent for something like this where the clothing shop owner has special interactions once she's corrupted enough to sell sexy cheerleader outfits. Even if you send your swim team to the beach as lifeguards I don't think they corrupt the beach anymore than usual (I mean, I had students who were treating it like a nudist beach and didn't really get any rep losses so yea) so that would be an idea where you could either get a good source of rep by keeping them competing or corrupt the town as they go out and show themselves. The church shows some scenes and talks about how it is "corrupted" in my file, but it's not like people are going all out or anything. Heck the mayor quest chain is an interesting dillema (I personally would side with the good guy over the corrupt woman, but if she made the town more corrupt over time then it'd be worth considering), except nothing is ever changed as a result of the chain no matter who is picked.
I guess I just want more content/quests overall and as I said I'm sure some of these are either on the schedule for 1.9.6 or may be worth considering in any future update, but I guess if they did want to add any sort of difficulty they could actually implement some kind of goal (that the player can enable before starting or not). Like, even if your grades are slipping and you have a bunch of naked students literally going at it in the hallways with low reputation, the schoolboard will just come around and go "tut tut" before slapping you on the wrist. The police corruption chain makes it seem like you are going to be under watch and in danger of being arrested but it literally stops until you get enough drugs to continue the chain. If you go up to the meanest dude in a bar to find information on a kidnapping and get beat down, the game sends you outside and lets you continue with no real downside. The 'worst/hardest' part of the game is the initial rush, the money wasted with the chem lab, and any major reputation losses due to said chem lab (either failure or mad science and drugging the town, even if you succeed in the hardest/fastest way you still lose reputation) or because your students are literally going at it in the public park. Maybe they need to implement a rival principal or something where if you don't have X amount of education before a certain month the game ends or something? Again, make this optional as a big factor people like is the open sandbox nature with no real limitations, but for anyone that does want a hard mode maybe make it more realistic so that rep losses are bigger or there is an actual goal you need to accomplish before a set time.
