While having a bog standard koikatsu graphics, this game has a lot of potential. I don't expect this to become a masterpiece, but it can become quite an enjoyable experience. For now, there are not that much content, which isn't a flaw in itself, but even that is enough to notice and point out some strengths and weaknessess.
Weaknesses:
1) It is very unclear sometimes what to do and where to go. A quest journal of sorts would be a great addition.
2)Most character designs look generic. Mother and Childhood friend have no unique clothes or features except giant breasts. Sister has probably the most memorable design.
Strengths:
1)Pacing is fast, no time is wasted, which is admirable.
2)Characters have nice personalities, although there wasn't that much time to explore them. No one is annoying or boring, which is surprisingly rare among games like this.
3) Sex scenes don't look awful and some have a lot of variety.
4)The general premise of the story is relatively interesting and unique, although it might just turn into a generic walk-around-the-town sex game.
There are also some bugs:
1) Love levels revert back to 0 if you save and load the game.
2)Some choices in the dream scene don't do what is written on them (the last one).
3) After some infirmary scenes it plays dialogue of the classroom (this lesson is so boring or smth like that).
4)You can go to school on weekends (idk if this is bug or not, but still worth to mention)
Overall, pretty interesting game, which I hope won't get abandoned. Good luck to the dev.
