Five Nights at Treasure Island is a game created by the developers. The original game was created by Matthew Phoenix Rodriguez, who later retired from working on the game and made Tia (aka Puritysin) the new developer.

However, Tia had also cancelled gave development, but did not make anyone else the official new developer. So the new developers (so far only consisting of Psychodash and Saturn) decided to step up and make a sequel to the first game that has tons of remakes.
