I plan to make a game with a story, but its theme will be different. This game is already over.
I wrote a bit about this game on my blog (the third idea). The plot of this game will be that the player chooses various objects, human traits and other things that can be fetishes. It will be a CYOA format to some extent. Transformation can be in this game, but it will not become the main part of the game.
I started working on this game, but before that I decided to make another game to learn how to make games on Twine. To do this, I turn one interactive story on an adult theme into a game. It is based on a very specific genre, the fans of which, I am sure, will be few. If anyone knows about the aryion site, you’ll know what I’m talking about. If not, I do not recommend even searching.
