Among the games that deal with hypnosis, this one caught my attention because it's not a light novel. It's about the protagonist receiving a message from an unknown number that turns out to be a female hypno who calls herself the protagonist's girlfriend and sends him images of the two of them fucking.
The gameplay consists of moving the hypnosis pendulum in front of Hypno depending on whether you do it right or wrong you get 2 different endings

I played it, I think it's a really cool game. The pendulum was a lot of fun to use, I hope to see something similar in other games. I found the writing to be really good as well.

I could only get one ending where Hypno herself is hypnotized; how do you get the other ending?

When you lower the bar completely, let it fill up completely again. If you do this 2 or 3 times, Hypno will get tired and take control.

My complaint is that hypno was too thin
