Well, i think it can be a fair reaction. It isn't a fetish for everyone and it can be from a small to a big turn-off depending on tastes.Watch out all this talk about futanari and someone will get their panties bunched up.
Frankly i always wanted to see some actual data about how many people like it, how many tolerate it and how many can't stand it. Possibly on a 1-10 scale to see how many people fetishes like this bring in and how many instead are turned away.
I myself have a somewhat low tolerance for it and when i see it added in an unskippable/nondismissable way to a game that i otherwise like a lot i wonder if the artist likes it or if he added it to lure specific audiences and how many are actually happy about the addition.
Luckily most game devs handle specific fetishes in a contained manner making it easy to avoid the enemies, events and characters that you don't want to see.
I apologize if it is a bit off-topic but i felt like it was a matter worth exploring. :V
To stay on topic i hope that the author focusses more on events/enemies and less on costumes. I feel that unless they are some sort of desirable cosplay/costume they add little and cost a lot of effort on animated assets. The costume he added for this game felt a little bland and he took a lot of time to implement it too.
