Get stuck in walls
In a few levels, there will be sets of rotating blocks blocking your path. (Example: Vanilla Dome 2 or Star World 1)Make sure you have a feather equipped. Use your cape to roate the blocks, then stand in right in front of the blocks while they are rotating. Usually the blocks will just push you back into open when they stop moving. However, sometimes the blocks will push you the opposite direction- into the wall. This usually works only in Vanilla Dome 2, but it allows you to walk down the slope of the wall underneath enemies. However, if you are surround by layer after layer of bricks (Star Road 1), you will be pushed into the other blocks, usually resulting in you losing a life.
