Sonic Next

A Sonic Next rom hack is currently unfinished but will hopefully be done eventually. You can play as Sonic the Hedgehog for the time being, and you will have to battle, spin, and hop your way through four stages and a boss battle. This game's level design is odd, but it is still enjoyable.
