From DIYgamer: "Our latest Q & A is with the team behind the title Devil's Tuning Fork. We've discussed the title before here at DIYgamer. The title is all about soundwaves, as you can only see your surroundings by ringing a bell; and even then it's just a sonar wave that passes and you're once again left in the dark. Trust me, the screenshots don't do the game justice and you really need to see it in action."
The article includes a link to download the game and features some interesting answers from the students.
