The Day the Light Shattered mechanic demo

This is a showcase of an important mechanic in a game that I am working on. You have to run around collecting 8 yellow balls (click them) that can only be seen when you are close enough to them. There are lots of red dots that can't normally be seen. You can press e to see them for a short amount of time, but this has a cooldown. Please tell me honestly if this would fit into a horror game. Have fun!
