Yes. I know these projects are huge but I can do it all by myself if I'm motivated by something. I used to have this motivation at time of development of CB. I don't know it could be because I was focused on that game only back then but now handling multiple things at once which maybe causing all this exhaustion.
Well once this project and other things are done will maintain a time table and avoid any unnecessary side work.
About the game it will play more like PiC. If graphics are ignored, I'm sure this game will be better in terms of gameplay and story.
I tend treat "H" content like adult mods and try to offer some gameplay to make it more replayable years later if find it in your library.
I think if the game is good and doesn't affect your pocket too much you won't mind spending money on it. I'm planning to release it on DLSite and Steam later to earn some more money.
