[Text-Based Story Game] Photopia

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.
