Dude, let me tell you a few things...
You, like most here, are a fan of this game, and you were certainly not satisfied with the ending of it, and I also believe that you were not satisfied with the way it was being produced, as were we.
About your fear of not pleasing. Dude, from what you've shown, you don't have to worry about that.
Some people deified Inusen, who made the game's art, I honestly never saw anything too much, if you want to see animations at a professional level take a look at the
sankaku complex. And from the videos you showed, they are, yes, very good.
You are sacrificing your free time to do something you enjoy and want to share with us. If someone complains, that person is just an idiot and envious.
And I recommend ignoring comments of this kind, although I don't believe they will have negative comments.
About the game and the delay. Look, I think it would be better if you split it into some parts, so you post as you complete each part. But don't post here, create a page like these here,
https://f95zone.to/threads/a-wife-and-mother-fan-game-final-pixil.62869/ ,
https://f95zone.to/threads/big-brother-fan-game-v0-13-fix-8-porngodnoob.19709/ , which are made by fans, and will not be breaking any rules.
That way you can post your work, and if people like it, maybe you can even do more events for the characters.
As for money, I don't recommend using platforms (patreons and the like), but I suggest finding some way, so that people who want to give some incentive, make a donation. I'm not saying a monthly fee, but something for a donation, and if the person wants to, they can repeat the donation the following month, without being automatically deducted every month.
About what I said above, your fear of not pleasing, try to do as I said, divide your game, put the first part, to see how people reacted, so you will know if you are on the right path or not, leaving space so people can also give their opinion, give some tips, suggestions, point out some things that may be wrong, or buggy. Something that is not possible, if the game comes already complete.
Anyway, these are just suggestions, but the game is yours, do as you think you should. And I wish you good luck, I'll wait for the scenes with my beautiful and sweet Linda.
