The game probably tried to do more than it is capable of and relies a lot on RNG for progression, which makes it hard to like. As well as being blatantly unfinished.
The setting is intruing, as you play as a boy who was raised and thus lives as a woman, with the needs of a boy. Overall there are 4 girls in the game with several unique scenes to them. However, the 4th girl doesn't have any "memory" scenes.
The girls all have 4 ways they can drain the main character, but they are all just recolors of each other.
You can move around and do stuff with the girls in different areas, but this doesn't really do anything other than change the first dialogue line when initiating the scene. Nobody will take note of your actions there or change anything about the scenes.
The special CG scene's art is very poor quality. Not in terms of drawing skills, but rather resolution, which is unforgivable for a game that came out in 2020.
Overall, any feature or content you see is flawed in some way. The gameplay and the experience overall is horrendous. It's important to note that the creator's latest game at the time of writing ("Manabiya" or "Schoolhouse") is way better. Even if you give up on this title, do not give up on games from this author.
