My entry for the solo competition is Photo Worlds. In PhotoWorlds you have to solve puzzles using a camera to reveal the true nature of the world in which you reside. Taking photos of the world will show you clues on solving the puzzle but you have a limited number of snapshots available per world.
I have the basic mechanic in place as of now (photographing objects in the world allow you to view an alternate texture when you look at the resulting photo). I’m not sure that I will have time to complete the puzzle aspect, unfortunately, but the process has been a lot of fun and I will be continuing development after the competition.
