IGN: "Sonic: Lost World isn’t about pure speed. The Blue Blur’s newest endeavor into the third dimension looks like his slowest outing yet at first glance. His normal gait couldn’t exactly be described as a sprint, and the breakneck, chaotic pace feels like it’s missing altogether as he jogs forward through the cylindrical levels.
But then, he runs up a wall. He flips over a tree, vaults over a low obstacle. He keeps his momentum going when, in past games, he’d be stopped dead in his tracks. He just keeps moving. It may seem like a small change at first, but the ability to keep the little blue ball in motion is perhaps the biggest change in the franchise."
