Let's break it down:
We'll still have three more parts of the map: the second floor, the underground, and the in-between worlds, which will be maps from FNAF 3 and parts of FNAF Security Breach that are destroyed. I plan to put "not-so-secret" areas where players can save their progress.
I was thinking of putting Mangle in the vents, she would appear randomly and could catch you. There'd be a random chance she'd either kill you or throw you into a place where you'd get stuck, and the Puppet would use you.
As for the scene, it's still a work in progress. It's been available in the game since the beginning, but it wasn't functioning. I haven't modified it much yet, but it will improve!
I'm good at modeling, but I don't think it'll turn out very well. In fact, all the models from FNAF version hentai are already available on a website, both from FNAF 1 and Security Breach, so I'll just keep using what's already there. HOWEVER, in the future, I plan to remake all the animatronics I'll include in the game and sell them for everyone to use.
And finally, thanks for giving ideas and making such an extensive comment! It helps me a lot to think of parts I either forgot about, didn't know how to do, or would be a good addition to the game. You're awesome!
