If the player throws 30,720 punches on the title screen and then starts the game, it will begin at the game's final stage rather than the first stage. This improbably large number is achieved by exploiting a quirk of the game's hexadecimal code, which normally only counts values up to 255. Rather than counting the raw punches alone, the game uses a secondary counter which updates by one every time the punch counter rolls over (i.e. every 256th punch): if the counter's value is 120, starting the game triggers the warp.

After obtaining the map from the karaoke bar, if the player selects the "じっとみつめる" ("Stare") option and waits on the resulting screen for an hour, a text box will appear mimicking the sign-off messages used by Japanese TV channels before the screen goes black. Waiting an additional three hours brings up a series of SMPTE color bars, and waiting one more hour brings up a second text box which simply reads "おはようございます" ("good morning"). Following this, the player is returned to the karaoke bar, with their progress reverted to before obtaining the map.
