"Island of the Lizard God" was inspired by the "Isle of Dread" D&D module, and the Fighting Fantasy gamebook "Island of the Lizard King" - both old favourites of mine. This year I flirted with various one-page dungeon ideas: a Call of Cthulhu adventure, a walking castle, even a fold-your-own random dungeon generator. In the end I settled on something simpler, something that spoke back to the classics. Plus, two dungeons on one page!
This competition gets hotter every year, so I don't hold out much hope of winning. It's fun taking part though, and combing through the other entries is always a great source of inspiration for my games. Best of luck to all the other entrants!
