Debug Menu
Power on the console and wait until the demo starts. Press A to skip it, then wait for it to play again. Skip the demo a total of four times. After the fourth time, wait until the title screen appears, and then wait until a blinking animation follows the titles name from left to right. Press the A Button exactly when the blinking begins, but before it passes the "T" letter in the name. If done properly, the debug menu appears.
Secret Ending
If you wait for an hour after beating the game, just sitting there at the ending animation screen, you'll find a new animation and a hidden message from the developers.
