Developed by the delightfully named Gopherwood Studios, Entanglement is a puzzle game with a premise not unlike Snake: starting in the centre of a hexagonal board, your goal is to make the longest unbroken line you can using the pieces provided. If you hit a wall or loop in on yourself, you're out.
It's a simple game, but strangely compelling. The perfect thing to kill time while with while you eat your sandwich today. Entanglement [Gopherwood Studios]
