Missing Trailer Scene: The studio released a trailer 7 years before the release of the game. Most scenes shown from that trailer aren't included in the finished game.
General Trivia
One of the notes about the bottle cap notifies about a certain monetary crisis. This means that the game, or rather, Raya's memory, which had its setting touted as 'being in the 90's', must have taken place between 1998 (when the Trisakti Incident and the fall of Soeharto and Orde Baru happened) and 2000.
Confirmed in the epilogue which takes place in the real world, where the former Doomsayer is now hawking t-shirts "for the new millennium", strongly suggesting 1999 as the in-game year.
