Before I officially start the post, To anyone who thinks Five Night's at Treasure Island's first demo is the first FNAF fangame. It's not, This demo was released on December 1st 2014 which is no where near as close as the date the Recently found game has. Now you are probably wondering "how did you find this game?" well I'm glad you asked. I looked in the Notes and credits section of Five Night's at Pico's (Nov 21, 2014) and the account who made the game "@DATProppy " credited a user named 3Ddeveloper who made a game called Five Nights At Freddy's -scratch edition-. Curious I looked at 3Ddev's Profile only to find nothing. So I used the wayback machine and I found it the first (Known) FNAF fangame released on (27 Aug 2014). Now because this game is no longer on the scratch website I used Forkphorus to get the project playable. This is honestly A very interesting find for sure. here is a video that talks about the find in a little more depth:https://youtu.be/8xNcKkCO1ZY

and here is the game it's self:https://forkphorus.github.io/#25952072

Let me know if you have found a game older then this one.
