I'm impressed, the game has potential that I haven't seen since Curious Tales of Yaezujima - Rinko Kageyama's Endless Summer. Good art, excellent effects, good graphic design, each NPC having their own dialogues, affection system with the kings, micro and sub quests, made this game beautiful and exuberant that can be filled with a huge amount of scenes and libidinous events in the future.
However, there are certain problems:
1. The story is very disturbing throughout the scenes, imagining that the son is feeling pleasure with the body of the mother he knew and even having relations with his own father in the future is very uncomfortable, not to mention that the mother is killed in a very brutal way.
2. Time will be your greatest enemy, the game seems to have a wide range of content and a lot of content, but I did some research and saw that it took more than a year to achieve what it has done so far, it's admirable, but it's not enough. You will need to be quicker in future updates, or what I would recommend is to lock in and deliver the game all at once, even if it takes 2 years to do it, the format and world of this game are too big to waste.
Suggestions:
1. Replace the mother's death with a kidnapping, it makes it simpler and less annoying, say that she lived alone and that the protagonist was raised by relatives, but since he became a young adult, he doesn't want to listen to anyone. So, add a perverted old man to live with the protagonist in place of the father, and that the protagonist has only known him for about 2 years, or something like that, it fixes this controversial beginning of the story.
2. Base it on games with similar themes, such as: "Curious Tales of Yaezujima -Rinko Kageyama's Endless Summer" and "Kamikaze Kommittee Ouka RPG", close to what I believe you want.
3. Lock in and deliver the game all at once, even if it takes 2 years to do it, the format and world of this game are too big to waste or make big content updates every time.
So, I say goodbye, I wish the author all the best and that he manages to make this game with incredible potential, all the tips are true and not offensive or corrections, I really want to help you.
Good luck, bro.
ps: could you add shota? It would fit too lol
