This week's free "App of the Week" is a beautifully crafted 3D puzzle game released and offered to the small screen gaming world by the good people at Bedtime Digital Games. Back to Bed is a gorgeous 3D indie title set in a wonderfully weird and creative dream world. Those willing to take on the challenge will need to use all of their wits and problem solving skills to guide the sleepwalking main character, Bob, back to the comfort of his bed.
