Snake meets Qix meets Flicky meets Gauntlet? Collect orbs to increase the length of your "snake". This allows you to encircle "food" orbs, which open the level exit when all of them are collected. You also have to avoid enemies, which break apart your snake when they collide with it, or kill you when they collide with your "head". But you can also drop bombs which temporarily freeze enemies, allowing them to be enclosed... just be sure to avoid the explosion yourself.
A very extensive debug mode can be accessed by entering this very extensive code at the title screen:
Up, Down, Left, Right, I, II, I, II, Up, Down, Left, Right, I, II (×2), I (×3), II (×2), I, II, I, II, Up (×2), Down (×2), Left (×2), Right (×2), Select
Note that this code must be entered after the title screen fully appears and before the game goes into attract mode. This gives you about 15 seconds.
Saves changes in the "OPTION" menu and exits back to the title screen. Note that you have to re-input the button code to access this screen again.
A graphics viewer for the game's sprites. Press Up and Down to scroll through the "groups" and press I to cycle through color palettes.
A graphics viewer for things like background/foreground tiles, title screen graphics, cutscene graphics, et cetera. The controls are the same as the "OBJ FONT" mode.
A basic sound test. Includes both music and sound effects. Press I to play a sound and II to return to the menu. There is also a "PCM CODE" option, but it doesn't play anything.
Songs are stored in sound codes 3A~3F and 70~79. To stop a song, play sound code 00.
Another menu with some debugging options.
Turn invincibility on and off.
During the game, press Select+I to choose a level. You can also hold Select and use the d-pad to move your character freely around the level.
Pause the game and press Select to advance frame by frame.
Displays your map position at the bottom of the screen.
Turn the display of the "pause" text on and off.

|A filler tile found throughout the "BACK FONT" mode.|
|Heart graphics intended to be a password icon.|
|This is the entirety of "group 17" in the "OBJ FONT" section. The game just uses the basic font for the "act" and "game over" text. A date and developer credit for Tsutomu Fuzisawa can be found below.|
|Sound Code: 70|
Likely meant to be a level theme.
|Sound Code: 74|
A slower tempo version of a level theme that actually is used in the game.
|Sound Code: 79|
Sounds like it could be a credits theme. The credits in the game don't play any music.
