The theme of the Game Jam is "Things are not always as they appear".
I couldn't spend too much time on this one, but I did manage to make an interesting mechanic. Objects can be manipulated in size by interacting with their shadows. Want to make a cube bigger? Go farther away from the light source to make your own shadow smaller in comparison to the cube, then interact with it to make the cube bigger.
The goal in the game (reaching a certain spot) was made up at the very end, not really justifying the mechanic.
