This doesn't really has to do with the game since I maneged to get the last version before it was removed, but it's important if you want to use it and know why the creator removed it.

Basically, from what I know, there was a drama about the creator being homophobic (not fully sure if it was that exactly, but I know it was about his opinion on something) and Fnaf Engine was taken down (a long his other stuff). After that, he disabled the comments on his profile and never talk about Fnaf Engine directly, at least for now.

Sorry if I sound more confusing, but I losted a comment that explained it better and get a reply from SealedKiller (the creator) isn't easy at all after that, but now about the part that can be very helpful for the people that couldn't get it:

I getted the last version (I had an older one) from Reddit, but another user reuploaded it here, which is easier than looking for it on reddit. Here's the link:

I recommend get it quick since it's it could get removed at some point, but I didn't see any complain from SealedKiller or anyone else, so who knows, luckly it will be there for a long time.

So yeah that was it, I know it doesn't affect the game at all, but I wanted to talk about it since many people have the doubt of what happened and how to get it again.
