I think I'm doing alright so far. I'm making a puzzle game (something I've never done before) and the idea is based on the way that things can look different in the dark. To be more specific, the silhouettes of objects can look completely different to what they actually are. So if you take that idea, you can make a puzzle game where you have to arrange objects in a certain way so that when the light is switched off, you have a brand new object that can be used to complete the level.
