A quick playthrough of Wing Fortress Zone from a completed save of the Sonic 2 Retro Engine version. The good thing about the Retro Engine is that you get to choose when to become Super Sonic as in the original you would become Super by jumping. Wing Fortress Zone can be a difficult stage as Regular Sonic if you follow the normal route but with Super Sonic you can pretty much skip the harder part of the stage by taking the upper route and skipping most of the stage. With regular Sonic there's a way to skip part of the stage as well but it's not as easy.
