The problem is the game is not finished and the code is constantly being changed. A framework to a splice character would not be too difficult to make; the difficult part is when Oni decides, "Eh, I am not feeling this way of specifying an object" and now all of your code is incorrect and must be changed. When he is done fiddling with the code, you may see a resurgence of modding for this game. But I would also like to point out that modding this game is not that difficult. Python is a very approachable language and this game is really 99% renpy and 1% python. So anyone who has a slight interest in modding this game, copy your game files and go to town. I think people have been scared away by all the "this game has spaghetti code", it in fact does to an extent. But the game runs and can be understood, so it can be modified... Anyway sorry for the mini rant
