About the development of deja vu:
"this game was originally created as a ordinary fan game, but then creating and thinking through the plot made it ynfg look a tribute and love for the original game.
once the project is no longer open and I fell into despair. in order not to lose my skills I started to create another fan game - spinOFF (OFF fg) with the same characters that were supposed to be in the first game. the protagonist would be different, but the main character of deja vu would have an important role in the plot.
but the problem was solved and the spinOFF stopped at the beginning of development."[1]
