I got name for this dream game from Nick Cave.
Game for two.
Player one is escaping an office building, he/she starts at top floor and must proceed downstairs and each floor represents a level.
Player one is navigating their way through office maze and zombies/demons come at certain moments. In the beginning, only one or two demons will arrive, but they are dangerous, they can kill you very quickly. At first you have only melee weapon, therefore you must hide from player two but as you proceed you will get also ranged weapons.
Player two is a ghost, invisible one most of the time. Their goal is to kill the player one, so they can haunt the place together forever ♥ However player one can resist, because as it goes in love, we always have a choice. So every time a player two shoots at player one, using something like a energetic laser, they become visible and hitable for the time they attack. Player two must find correct timing and tactic when to attack player one, cause they will either run away or kill them. If player two decide not to hit player one for a certain amount of time, they will lose their ghost awareness and disappear/die, so they must engage with player one.
