Extra Lives - Go to training mode and spell the word FLIK to gain a
life. Repeat as desired. When you have enough lives, exit training mode
but don't save. Instead, start a new game.
Invincibility - When the level description appears, hold Z+R+L. Repeat
this at the beginning of every level.
Level Select - To get the Level Select, go to the main screen. Go to the
ant hill and hold Z and all the C buttons and press R. There will be an
arrow pointing right at the bottom of the screen.
