If its okay i would like to give my opinion to your opinion.
1. Yes the prologue is more or less "long" but the dev already made it "shorter" and you even can skip the male (second mc) perspective. Yes i also think half of the chars in prologue won't be important but i think the dev has his reasons and every horror movie for example needs some flat characters to die and there make the world more "believable".
2. models are nice and the women looks great! big but not too big tits and also a still healthy and not unrealistic body. i don't know where you are coming from here even i accept your point of view. too many games have way too thin/immature looking women/girls without enough curves in most games or they go the extreme way and make everything totally crazy (ugly faces included then)
3. lesbian... why? i don't play male mc games and expect a gay route. where is the sense in that?
also there are plenty games with enough lesbian stuff even i think lesbian route is already implied by the dev and i bet there will some sort of optional lesbian route even the game doesn't need it in my opinion.
4. since this is no point of importancy for me personally i won't argue with that. but i think it also involves the rooms and future content.
5. you mean a "skip to next event" button?
