This look promising, the writing is correct even good, the animations are smooths, rare thing for an aicg the image and characters are pretty consistent (by that i mean the clothes don't switch colors or shapes randomly things like that), alll in all a pretty good start. For that bad part, the story feel forced sometimes, the stepsister and stepmother are both annoying af at best sadistic manipulator at worst, the MC not fighting back even a little feel very "the story is going that way even if it don't make sense". The stats are also very confusing, never said what they represent really, are they important for the game ? will we get different endings depending on them(slut end, romance end, back to a guy end...)? do we need a certain amount to reach some scene or make some choice, doesnt feel like it for the moment ? If it was explained i really want to know, and if not could some patreon or the dev gave some info if they have them, that would be nice.
Well good luck dev, there more positive than negative so you are on the right track
