Hello, I'm Christian, the main developer of Five Nights at Froody's 2. Back in the middle of March, I was getting ready to release the game, but, the computer I was using to make to game got too old to even work properly. This meant that all of the work put towards this game was gone.
I've bought a new computer since. I had to start all over again. However, as of now, I'm more than halfway through completion, so I don't expect there to be any more issues.
I would suggest you use a cloud storage site like mega or mediafire as off site storage incase your computer has any more trouble that way you have it backed up to X point and then do not have to rewrite the whole game
