one really cool cheat: in world 7, there is a secret level by finding a secret goal in one of the levels leading to a vine. after you beat the secret level, a path opens up which creates a shortcut in the world 7 castle.
You have to get red flags on the level next to it.
You have to finish a level with the secret goal on the level closest to the cannon.
In each level, there are wo exits, the main exit and the secret exit. Mohamed Hage
