Gonna copy my questions/feedback from the ULFM forum here, seeing that the creator is more active in this forum:
About the alpha version I can't say a lot, well the design and graphics are good I can say that.
But what I can do is ask a bit about the system:
-First of all you define the game as a "Classic visual novel and dating sim gameplay", on this point I suppose then that we will have a few stats, so the question would be if it will be the usual stats (strenght, agility, intelligence, charisma), something more personal (assertiveness, sex skill...) or perhaps a mix of both.
-Another thing that I would actually ask for more information is about the "Complex nonlinear plot", if I take it right it means that with a character there will be quite a few outcomes depending on your choices. However one thing that I would like to ask is if the game will take into value the "inaction", I will explain myself, if you do nothing during the game will the world remain frozen until you find an opportunity/quest?, the usual thing to solve this is to have a standard route that plays by ignoring x event for y days. For example if you don't help your classmate (be it because you are a coward or never found the opportunity) she would end up raped, if you ignore it she would end up as the group sex slave.
-How is the game planned to end a walkthrough?, I mean will it end as many dating sim after getting a girlfriend and solving her route?, will it end after x days have passed?.
-Finally about the romance I have to ask if it will be with dates and a use of money with slow romance or if it will be a fast romance (to give you an example with a similar game summertime saga is what I take as a fast romance).
Those were a bit of "general questions", but the big ones are under the fetishes because some of them as you may understand leave a lot to imagine:
-First of all we have the femdom fetish, the big question is if it will only affect certain girls and if there will be routes without it. I would say that the most important thing to know is how far will it go, meaning if for example a girl will use a strap-on to fuck your ass or if it will be more on line of the girl being dominant in sex.
-Second one is the corruption fetish, again if it will only affect certain girls or will it be more "overall", it is kind of asking the same as the last question, how far into it will we go?.
-Third is obviously about the BDSM and it's again a repetition of the other questions.
-Fourth is about the cuckold fetish, ok this one is actually quite complex, same questions plus the following, what will be the motive that will generate the fetish?, usually cuckold is a fetish that changes a lot the feeling depending on many things, like the motive that generates it (blackmail, rape, seduction...), how it ends (if you can make the girl stop having sex with the guy or if it happens once it will continue until the end of the road)...
-Fifth is about the humilliation one, will the boy be humilliated or the one doing the humilliation to others (or perhaps both?) and if for example the school bully will humilliate other characters.
-Sixth is about hypnosis, it is almost as complex as the cuckold fetish in questions, how will we use the hypnosis on the game?, will it be to increase affection? have sex? or perhaps influence the mind of a character?.
-Finally bisexuality and lesbians, the first one is kind of straightforward, forget the pun hidden on that, but the thing is if the game the male x male scenes will be with the trap boy or absolute male x male, about lesbians to tell you the truth I just don't know what to expect, will it be a consequence of a route? will there be lesbians since the start of the game? is your sister the lesbian?.
I think all of the questions of the fetish side is quite important that they are answered because it's what people are attracted to at the start and well, perhaps the content can be gated at the start so that people don't feel scared about finding a fetish they don't like. Personally I don't care about it because I like to be able to make mistakes and that bad things happen (one of the worst ones for me would be to have the bully fucking you in the ass, if that was added I just ask that I can get a revenge option under x conditions, revenge!).
