A rather repetitive game that doesn't allow you to shoot up or down making shooting down enemies tedious.
Level Select#
At the main menu, highlight "Normal" and press A twice. "Easy" should now be highlighted. Press and hold A, and "Normal" should now be highlighted again. Press and hold C+Start (while still holding A), then press Up up to 7 times to choose a stage (pressing Up 7 times skips to the ending). A sound effect will play each time Up is pressed. Start the game (the difficulty level can be changed to the desired one at this point) to start at the chosen level.
