So, this is a very specific kind of game. The kind that has "Hypnosis" in the title, and is a straight VN with minimal choices. The hypnosis-content is what you're here for, and the game doesn't really offer anything else.
The plot is some high-school vanilla-romance pulp. MC-kun gets a full personality in this, but sadly the two girls need do with half-a-personality each. The school-scenes could probably be written by AI these days.
Translation is bland, with some awkward typos, though obviously you shouldn't judge too harshly with a labour of love like this.
The actual draw here are the hypnosis-scenes, which are "realistic", while still being idealized. If you have this kind of specific thing for the process and fantasy of MC, then you are the target audience. It's the exact thing that makes this story worthwhile. Hypnosis is not just a means to an end, but a key theme in this. Be aware, though, that the game takes a very "dubious consent" -stance on sex, and despite the vanilla aesthetic, the sexual content itself can get rough really quickly. Japan being Japan, basically.
Overall a rough experience that will only please MC/Hypno enthusiasts. I personally leave the text on auto and do something else while the filler-scenes are playing out.
