New idea for the third mode
Memory Mode
It's similar to nightmare mode but before you can do anything the game gives you 20 seconds to memorize the 6 number ID and the entry request.After that you cant check the ID or entry request and you have to use the folders.If you guess if its a doppelganger or neighbor right you stay alive but if you make a mistake you die like in nightmare mode.At the end you encounter the memory-man.He asks you to play the game called "memory" best of 5.If you call the D.D.D he will just dissapear and re-apear when the cleaning process is finished and the D.D.D will say that the cleaning process didnt work.The memory-man tells you the rules: 1.its best of 5 2.You get one turn. 3. you pick 2 cards that are flipped. 4. if you guess it right you get a point. 5. if you guees it right you get another turn if not its his turn.If you lose its game over if you win you defeated Memory Mode and get a achievement.
