"Toy" Brainstorming

Essentially, this "toy" is a mechanic that we think would be fun to play with. Here are my ideas:

• Light beams. Basically, I see this as sneaking between areas so the light doesn't touch you. If it does, you die. I was also thinking of throwing in some mirrors so you could redirect the lights to distract you enemies. 
• Phasing. This one would be where you have the ability to phase through various surfaces. 
• Night vision. Using a night vision camera, you can see certain things that you couldn't if it was just the normal camera. 
• Gravity. I'm picturing this one as the character has gravity abilities which they must use to navigate the terrain  and solve puzzles. 
• Hydra. The main goal of this would be to sneak past enemies without killing them. If you do, two pop up in their place. The more enemies, the harder it is to get to your goal. Killing could also be switched out with spotting. 
• Thermo. This would be where you used a camera to see peoples body temperature. You would ask them a series of questions to see if they were lying or not based on spikes. 
• Magnetic grappling. By collecting a certain amount of energy, you would be able to use you magnetic grappling hook to get to places you previously couldn't get to. 
• Energy shields. This is a race against time. You have to get to the end of the level before time runs out while also dodging projectiles. Your one defense is the energy shields. However, the more they get hit, the weaker they are. 
• Phantom. Travel between the earthly and spirit planes while wreaking havoc. 
• Teleportation. Need to get somewhere quick? Use your nifty teleportation abilities.
