Control the character with WASD and point to the 'proton pack' the character is holding by using Q and E. To shoot, press the space key. If you point in the direction of one of the ghosts, it will stun it. To trap the ghosts, press 't' to make a trap appear at your feet. Press t again to make the trap activate. With the proton pack, stun the ghosts and drag them into the beam to trap them. Once you have all 5 trapped, you win! However, you could only activate the trap ONCE.
Thanks for the Ghostbusters series for inspiration.
