Failing a mission occurs when the player either dies or runs out of time. The player is then shown a screen that displays the number of chances left (the game's term for continues) and is given the choice to try again, quit, or enter a password. The game allows the player a total of three chances. If the player chooses the try again, one chance is consumed and the player is returned to the level select screen and allowed to select a different level or retry the same level. If all chances are used, the game is over.
