I had high hopes for this game on a conceptual level, as player mind control is definitely a fetish of mine. Most of the character designs are great even if some of the Riru shots during her first scene look sorta off. The dialogue is good and believable in most cases(though as you may later learn if you continue reading this text wall, that's not always a good thing.) But the treatment of the player character, the lack of stuff like food(severe hunger pangs from lack of food are no joke and a severe trigger/turn off for those who've ever gone hungry), proper bedding, or actual push-back and/or snark from the MC seriously pushes all my "DEFY, RAGE AGAINST THE COSMOS, BE A FONT OF CAUSTIC HATE" buttons. And lets not forget the the fucking Bomb Collar. Though that might have been a lie iunno, the blood splatter & various organs would make it obvious as to his biological nature & the fact that she had a bomb in a school & killed a functional human male would end her in some deep shit. The glued on boxers are sorta of a nonsensical addition which could be circumvented by anyone with a brain or sufficient pain tolerance(Sure as hell wouldn't stop me, when you've gotta go you've gotta go. And as shown soon after, the magic boxers don't hold in liquids)
Which is weird, as I usually enjoy femdom content. Maybe its that the objectification isn't of a sexual nature, and instead being a denial of humanity & sentient rights(This is less of an issue with most of the characters as it isn't knowing or intentional on their part, but even most subs won't go along with that sort of thing unless they actually feel appreciated.) In most Femdom games stuff like abuse and mistreatment as mentioned above are usually either handwaved or used as a plot point rather than being played straight and having the MC actively resentful. The only games that include it actively include physical abuse or BDSM as core fetishes, again, main plot point. It causes me to constantly think what I would be doing in that situation, like hashing out an actual employment contract with Rea if I decide to still hold up her charade(accompanied by threats on both circumstances that I would have pre-prepared for... Obvious reasons.)
Overall, the MC feels like an abused Harem anime protagonist, silently accepting situations actual humans would never put up with. And hey, this might just be a me thing. I have Invictus in my sig for a reason. But it's something to watch out for.
