Easier way to complete the upgrade challenges

This can only be done once you get the Pegasus Wings

When you enter an upgrade challenge you must dodge flying tiles for a certain amount of time, and when you do this you recieve and item.

Well, after you recieve the Pegasus Wings fly to the top of the level and hover there. By doing this you will be safe from the tiles (they wont be able to reach you). do this until the tiles stop, and pick your prize.

Erase saved data

Here's how to erase your saved game. At the title screen, simultaneously press Left, B and Select. You'll hear an explosion type sound if it's done correctly, and your game will be erased. This is a good thing to do if you want to sell your game but don't want the next buyer to have an easy time of beating the game..or if you just want to start a new quest.
