Feature-list Detail

  • Move your ghost through walls

The player can move through walls that are on the play area. The whole play area is surrounded by a set of thick, impenetrable walls. If the player moves through one of the penetrable walls he loses ektoplasm.

  • Manage your ectoplasm storage

Ectoplasm is your health bar and your indicator how many walls you can go through. Ectoplasm gets reduced by moving through walls, getting hit by ghost traps and attacks from ghostbusters. You can restore your ectoplasm by consuming ectoballs.

  • Stay hidden from the dangerous ghostbusters

Ghostbusters are patrolling the maps. They have an area of sight and are reacting to loud sounds – like toppled furniture. Patrolling ghostbuster have green glowing eyes. Aggressive ghostbuster have red ones.

It is not penetrable and deals a big amount of damage to your ektoplasm. Can be turned on and off. The Ghost trap, to capture ghosts. Holds the ghost for a certain amount of time. Alarms every ghostbuster in the area.
