The Day the Light Shattered mechanic demo

This is a demo version of a key mechanic for a horror game I'm making called The Day the Light Shattered. You have to collect 8 yellow balls that you can only see if you are close enough to them. There are red dots that are normally invisible, but you have the ability to see them for a short amount of time. Would this be a cool mechanic to have in a horror game? #horror #other
