HOW MANY ALIENS CAN YOU SHUT UP? CAN YOU SHUT UP ALL ALIENS?
Unused Graphics#
The graphics for the lower part of Otapyon's jumping frame are stored in the ROM twice for some reason.

The game's character set includes a heart symbol and a set of arrows which go completely unused.

Leftover Development Code#
Holding shift and typing TOKUSAN while the game's intro plays will cause the game to reset when the intro is done. This doesn't appear to have any other effect. The reset operation is achieved by restoring the Z80's stack to a state that it had while initializing the game, so this probably had more of a purpose during development.

Cheat Codes#
Pause the game and hold down C and H simultaneously to go directly to Level 25.
