	Various Steam Achievements...

Do this while immortal, either through shield or dying. Select a level with many magic missiles. Allow them shoot you to become immortal for a short time. Dodge the other magic missiles. Along as you are immortal, they will do a full circle around you. Playing at a higher difficulty setting will result in faster missiles.

Select the Easy difficulty setting to eliminate the time limit. Start a new game or continue from a saved game. Choose any desired level. Walk in any direction. Facing a corner or wall is acceptable, as miles are counted from your movement and not actual travel distance. Use an object to keep your movement key or controller button depressed and allow the game to idle in this state.
