Brainwave!

Okay so a particle of inspiration collided with my brain on the way home this evening and I thought of an additional mechanic to go with my cloning/teleporting/respawny thing. The character can not only send out their life force to reanimate piles of junk but they could send out little probing version that when they strike other object create certain effects, e.g. shooting a charge at a spotlight could reveal blacked out sections of the map or shooting a smoke machine could reveal laser tripwires. A charge could be shot down an electrical socket and a maze-puzzle could take place as the player navigates the charge down the cord network. If the player lacks an attack mechanic then they would be required to use items set in the environment to trick or eliminate foes.
A good targeting system I saw was similar to that of Missile Command was from a game called Intrusion 2. Not only does this game have a series of amazing boss fights but it is very simple in how the player plays the game.

The yellow triangle is the targeting cursor which the player's avatar shoots at. It is simple and effective and allows for accurate aiming. If the game required the player to make shots under pressure then the point and click style works well.
