Photopia is an interactive story about Alley. Hailed by many as being a pioneer in text-based adventures, it's also known as one of the best. Although the story is very linear, it is a truly provocative and fascinating one, and masterfully told. Play it through; It's a story you won't soon forget. I recommend using choosing color.

Since it's easy to get stuck, here's (http://ifarchive.giga.or.at/if-archive/solutions/photopia.sol) a guide that doesn't give too much away as far as the story goes. Still, try to use it as little as possible.

Best game ever.
