2-3 puzzle exit?

Answer from: BlueJackG
You have 2 exits in this level, and you have to take the same path for both ends. Once you enter the maze, drop down the hole in your right. next go right as far as you can, you'll reach a red door. Ignore it, and drop down the nearest hole. Now go to your left, pass by the enemy blocking the way, and drop down one more level. And after that go left again, you'll reach the end of the level, and, if it's your first time here, you won't be able to get out. Keep going, solve the last puzzle, and you'll find one of the comet pieces. Come back to the level, do the exact same thing, and you'll end up in a higher platform with a red door. Solve this puzzle and you'll get the second Comet Piece.
So, Resuming:

Right, Right, Left, Left, *bis*

and done!
