To unlock worlds 9, and 10, you need to beat every single level without getting one continue, and I can't seem to do it. I cannot find any cheats to help me get through this, and on this one youtube video (of which I can't seem to find) they used a little technique of exitting out instead of continuing, then going back into the game with the 3 lives they offer to you right when you start a world; I tried it, and it didn't work.
So, do you guys know of any cheats, or glitches that'll help me get passed this?
