Wow. This was a unique experience. It's all VERY specific kink stuff, but some of it I knew I was already into. Of the new stuff I didn't encounter before, some of it was too weird for me, others were right up my alley due to already being another kink of mine, others I just enjoyed alongside the kinks I was into.
Is it perfect? Well, I was disappointed that the other two girls weren't naked more and that the exhibitionist one didn't stay naked after her part was over. There was also no mention of her exhibitionism kink in her epiloque, which felt like a waste of unique character traits.
The guide also broke things up so much that I missed three secret optional stuff because I just had too much to juggle as I went through and couldn't go back for them. It would've been much more manageable had the guide included the optional/secret along the way so that you don't lose track swapping back and forth between the sections of the guide.
All in all, it's a really great game. I enjoyed it from start to finish. Especially since it caters to some kinks that are incredibly rare in hentai games.
