Mr Smee provided the heads up for Devil’s Tuning Fork. Which is… well, striking, to say the least. It’s an Echo-based first-person indie puzzle game. Get it from here or watch it beneath the cut. When your main influences are the optical illusions of Escher and Dolphin’s echolocation, you know you’re onto something. From a team from DePaul University, this is probably the most striking conceptual indie 3D-puzzle game I’ve seen since… ooh, Narbacular Drop. It’s also profoundly atmospheric and a genuinely unique aesthetic. It’s got “Must play” written all over it. Or, at least, it’s got “Must play” written in a blog-post about it.
