Some lenghty feedback on the game. I played until about the second girl visible on the ring thing. (Some SPOILERS below).
It is fun so far and the animations are fantastic.
There should be some kind of "warning" in the game, that a big vn style introduction is going to happen before the game play loop. (Yeah it is written on the game page somewhere, but who reads those). Also I do not think, this is called sandbox. Having "quests" and a progressing story is rather the opposite of sandbox. It is management and dating sim what I could see so far. I dispise true sandbox like minecraft.
The english grammar is an eye sore sometimes. Every pronoun in English that is not refering to a person should be "it". The family avoiding option is not consistent. There are still words like bro in the text. What you type for your relation is also used for the mayor and the vice mayor. The non family relation words are not capitalized where needed. Why not just have one alibi question at the start that explains, that mc is adopted by his foster mother (or not. hint, hint) and have the text done consitently, if blood kinship is an issue. Also, it does not make sense whatsoever whenever mc claims that it would be wrong to lust after ones room mate. Bah. Roommates and childhood friends hooking up is pretty vanilla. Also, it would not be forbidden love, and the cat goddess claimed, that it would be more valueable when it is forbidden.
Quality of life is lacking. No X button to exit dialogues is a big start. But there are too many useless clicks. I keep constantly pressing control to skip the mindless repeating stuff just to traverse locations. The fading in and out adds to the time. Having doors act as the button would be more immersive. Also going to the field, as you would go to the storage without involving the town map. And what I will never understand, why in vn games there are often several dots used as a text option. I talk about clicking like 5 times, just to work on a field and seeing . .. ... as the dialogue. This is not fun for repeatable scenes. Also, scrolling through the town map is ... not very map like. It is not random access, like a map. It is sequential access.
Character motivation put me off in the second "conquest". MC already knows from experience that he has to make the girl orgasm. His own fun has nothing to do with the harvesting. So when his second encounter offers her v-card ... why? He should at least offer to only make her feel good, after she could reply, that this would not be true love or some nonsense excuse. Also, he is not really experienced at this point, so actually putting it in* would have the risk of him getting soft before she reached her orgasm, and as such failing in the task of harvesting true love energy.
* using up his own v-card, as far as I knew. Can't remember any establishing of his previous sexual expericence. His first conquest did ask if he left a girl-friend, which he denied.
