I just finished reading it and I really enjoyed it. The last CGs were really good. And man, the downwards spiral they all got themselves and will keep each other into.
I don't know if you're planning to update this game with more content, but it would certainly be interesting to explore these characters more, maybe adding new choices that don't lead to an immediate bad ending but rather branch out the story, perhaps a route in which the characters can escape the fate of loosing themselves, confront Anny's actions. Maybe paths that could either lead to character development and a good and healthy ending, or lead to one or all of the characters succumbing to a different but similarly life shattering hypnotic fate.
Either way, it's great to see more hypno content with effort put into the writing and that actually focuses on the hypnosis kink rather than just using it as an in-universe tool for sex.
You got yourselves a fan.
