The old-school spiky blue hedgehog gets a day/night split personality in his latest caper. By day, it’s classic high-speed smash, run and jump racecourses; after sun-down, Sonic turns werehog and tackles more jumpy platforming and arm-pummelling combat. The hyper-speed, super-bright day levels almost make up for the sub-par night levels.
