I've been playing this game for the last few updates and finally found time to comment on it. First thing first: for fuck's sake, cut the author some slack, will ya. The game has some flaws but it is far from "worst game ever", "cuckfest"... etc.
The way I see MC is as an average awkward/inexperienced horny just-out-of-a-high-school teenager with a huge crush - so him acting like a complete Casanova would actually be quite out of character. Now, I admit that getting blue balled all the time is starting to get a bit tedious though, so it would be nice if author throws us a bone soon. As for him having the smallest dick - I'll be honest, I didn't really go back to check but as far as I recall, he has a perfectly normal dick (and the only one I remember being bigger was a t-girl's one) - which is actually a bit of a relief after seeing MCs in some other games walking around with anatomically impossible tree trunk sized cocks which would caused them to faint every time they got a semi.
Main point of this game is - as the name rather obviously implies: many different fetishes - which of course means you'll find some that you personally dislike or even find disgusting, so bitching about them is quite frankly rather idiotic. I personally love the concept and hope to see many fetishes which are otherwise usually neglected - but I'm not sure if giving people Game over if they weren't adventurous enough was a good idea. Same with the bonus scene for those who had max points - it seemed a bit silly to be able to see a random scene just because of that, so perhaps having an app reward you with a scene in a different way would be a better approach...
Now for our main crush - I'm not particularly fond of her, though she looks nice, but most of us probably had a crush like that when we were young - a girl (or a guy) you were head over heels for, though she (he) might not have been anything special if we look back now but at that time we'd give everything to be with them, so I don't really feel there needs to be any special justification for why MC feels that way. While I'm not fond of games forcing me to like someone, it is impossible to tell a story without at least some rails though.
All that being said, I must say I did expect a bit more from the last update, since it was rather short. I have a feeling that the current update schedule might be a bit too ambitious. Perhaps author might want to consider releasing larger updates but less often?
So, to
ViNovella : continue the good work and don't be too upset with negative comments. There's always room for improvement but you'll never be able to satisfy everyone and there will always be a few people that will act like dicks.
