A late congratulations on the game, dev. I haven't played the game yet, but from the initial comments and reactions, it seems like we have a pretty good new corruption game. I've read the entire thread and I do really like what I see so far from what you have been replying to people, although I do have a few questions for you about the game.
1. The most common transformation seems to be a succubus. Usually a succubus isn't a creature known for having a single partner due to them extracting energy through sex. Is this something the game takes into account or is that not how a succubus works in this game world? I know you said that the only man involved in sex scenes will be the mc, but I do want to make sure that the girls won't be fucking around off camera before I get too attached as I often do. (I don't care if girls have had sex before they get integrated into the harem, only afterwards, I think it would be pretty stupid to demand all girls be perfectly pure maidens, especially in corruption games.)
2. The corruption in this game seems to be more physical then anything else, and so I would like to know if the girls will keep their personalities, or at least parts of their personalities once they have been fully corrupted. Too many games seem to just ignore a girl's initial personality after the corruption is complete and just assign a generic "super slut" personality to her. personally, I guess I don't really see an issue with this other then that it is kind of immersion breaking to go from a shy sexually repressed girl one day and the very next day, an extroverted sex fiend, and even if you plan this for the girls, please at least have plenty of scenes of the girls adjusting to their new feelings and body, maybe not being 100% sure of themselves to keep the immersion at least a little coherent.
3. You said that tentacles were planned at one point but you ended up dropping the idea for now but could return due to a patreon poll, if those return will they be optional? its just really turns me off pretty bad so again, I don't want to get too attached to a game that would give me that kind of surprise later down the line.
To add to this, I have a tip for you, or well more of a suggestion. This is your game, Dev, please don't give patreon subscribers full control of the game's direction. I've seen it happen and its not good, and I've heard (but not seen) that it's occasionally completely destroyed games due to massive direction swings mid development, or alienating the original target audience. I know it can be hard to not please the people funding the game, but you can give the patreons certain concessions like polls about the looks, clothes, personalities and the corrupted forms of characters, alternative (or supporter exclusive) character outfits and looks, future sidequests, optional (or supporter exclusive) content and scenes, stuff like that, designed to let the supporters have what they want without having to make a direction change mid development, and please make sure to not go into a death spiral of adding nothing but supporter content and ignoring your story, add bits of supporter content in with the main story updates.
I wish you the best of luck on your game, and I am very excited to see how it turns out, and as a lover of all things of Hellenistic origin and the age of antiquity, I love the aspect of a pantheon based on the Hellenistic pantheon so that's also got me excited. Also I'm sorry for the wall of text and opinions.
