UPDATED REVIEW
I can't give this game more than 4/5, and that's with full credit for its kinks many of which I happen to be into. When I wrote the original review below I had completed maybe half of the content -- it's hard to tell how far you are through the game. But the second half drags even while introducing new characters; the author just doesn't write compelling women who sound distinct. Instead, each girl is basically a scene dispenser with not a lot of build-up. Sandbox becomes increasingly tedious to the point of being a huge grind by the end. I usually like sandbox games but this is too much.
Futa as a genre has the potential to introduce gay/bi content, and this game is no exception. Where I have a problem is that this game is (1) very adventurous on that front (gender-bending, body swapping, futa on male, you name it), and (2) inconsistent about how well this content is gated off for players who don't want to deal with it. Some parts are outright gay, involving no futas or women at all and multiple men. This is going to be off-putting to people and the game really needs an intro section where you pick the things you just don't want to see up front. (Especially since some of the secret images are triggered by following various choices, and a few of the choices aren't super obvious about their content -- looking at you, three futas in the club.)
As far as MC goes, I agree with the reviewer below that he's too gender-ambiguous to be easy to identify with. This game is fundamentally a switch (in the BDSM sense) game leaning slightly sub, and catering to a dom audience only in bits and pieces. MC never feels "manly" in a real way.
The story and character development are both just weak -- meaning, nothing grabbed me. Meg is my favorite character and had some genuinely sweet moments, but it was too little too late: all the other girls sound the same, we get a constant supply of new, poorly-developed characters with a small number of scenes, and there's never any chemistry beyond superficial "wow we're such a hero" fluffing that doesn't ultimately count for much. MC isn't a believable hero and the girls seem to know it, but I guess they're willing to indulge him anyway. It's pretty bad on that front.
All of this is a shame because my comments about futa bondage/chastity stand: it's got some hot moments and a strong sense of adventure, and that's why I'm giving it 4/5 instead of 3/5. It's just extremely mediocre in plot, character development, pacing, and gameplay, and I ended up dropping it because it's a chore to play through and I lost my patience with the wet washrag of a main character. Great renders and theme, but everything else drags it down.
ORIGINAL REVIEW
Solid 5/5 if you're into what this game is offering, which is futa + bondage/chastity.
If you're into futas with chastity/bondage gear and dom/sub switching (your choice scene-by-scene which role you take), then it's pretty much unmatched. Even the match-the-pairs minigame is hot just due to the card images. The game has flaws, but nails this kink so hard that it's 100% worth it. (Note: you have to go pretty far into the game before you get to the good stuff, probably 10-15 hours.)
If you aren't into these things, then it's probably a 3-3.5/5. The pixel hunting to find secret images is a little too fiddly, progression is awkward, and it's not always obvious what impact your decisions will have (fortunately they're quick to observe, so you can roll back easily). MC is also a self-insert who has a stupid amount of plot-social-capital. I can suspend disbelief to an extent, but this game really strains it.
So yeah, I love the futa-bondage aspect and it's a 5/5 for me because it's rare to get a game that does it so well, but if this isn't your thing then I think you'll find it to be pretty meh.
