Solitary Sand, a text-based survival game

Solitary Sand, written in just two days, has no graphics, only audio: you're blinded after a shipwreck or kidnapping, and must explore an island with only sound and descriptions of touch sensations to guide you. It's not interactive fiction: you navigate with an FPS-style control system. You can pick up one thing at a time, and there are multiple endings. Unfortunately, all I've managed to do is find some rope, garbage, driftwood and a strange metal object. Then I drowned. [Ludum Dare via Free Indie Games]
