Earth Light

Debug Mode
To activate Earth Lights debug mode, hold Down+B and press R' on controller 1 three times during the intro.

Options Menu
After activating the debug mode, hold Left on the D-pad when starting or continuing a game to access this menu, consisting of a stage select, sound test, and the option to make enemy units either human- or computer-controlled (this can be changed ingame.)

In-Game Menu
Activating the debug mode will also cause the text "DEBUG MODE" to appear above the in-game HUD, along with the current coordinates of the cursor. From here, pressing R on controller 1 brings up the in-game debug menu.
 * Remove Unit removes any unit that is currently under the cursor (including friendly units.)
 * VS switches between human and computer control for enemy units, the same as in the options menu.
 * Normal Move/Multi Move allows you to move units an infinite number of times per turn (although the maximum distance per move is still the same as before.)

Pressing R again exits the menu.
