Do I really need to say more than that? Not only does it look like it breaks up the entire pacing of the game, but I cringe every time the player attempts to jump with his minecart, and falls short due to some invisible wall.
Why SEGA felt the need to lift Loco Rocco, and put Sonic into yet another zany overly complicated contraption, I have no idea. Are you still going to pick this one up despite the above video?
Edit – That was not me in the video.
