Oh well if you get your own visual novel off the ground feel free to send me a link! It's always fun to check stuff like that out. I was the same as you with this game. Always had neat ideas but when it came to implementing them and seeing how they could change the story a lot of them got put on the sidelines. It would have added a ton of time to development and they're not necessary, so for now they're left as just ideas. But maybe they'll still get added in later.
I used to be pretty terrible at art too. You should have seen my first few artworks and even the early art for this game. It was pretty terrible. It took a lot of experimentation to make things look halfway decent. Now I'm pretty happy with things but it still takes FOREVER for me to make any art. So while I'm happy with the result I'm still not that great because if I were a "real" artist it should take only a tenth of the time to draw.
And there's no need to support me with money :3 Messages like yours are everything I could hope for when I make stuff like this. Knowing I made something that someone else enjoyed and hearing about it is way better than any payment could be.
