no trouble, the creator is clearly in prison serving time for "other" content he was dealing with. not every country in the world will allow you to deal with stuff like these and "other". people shouldn't forget that most of the stuff here like characters and animations are from a game engine, he did a good job with what he had, and I really liked this game. but it's one of the so many games on this site that do the same.
anyone really wants to keep this game going can just recreate it in his own version and gg, no stealing and he can just keep going. but again, no one is gonna come to reclaim this game. you can copy paste everything via Renpy, you think the guy is gonna come back after 2 years and just reclaim all the new content? he will get his old game version, and then we will have 2 versions of the same game LOL... what's not to like here? the original can keep going whatever path he wants while the new version will start working backwards to have a complete game, maybe change how characters look and that's about it.
the law is very clear about this, at most the new dude continuing the game will be forced to change a few stuff and lose the original content which will force him to either recreate new previous content or just not give a fuck and have his game start when the original ended.
