Atari 7800 version

On the Atari 7800, the name of the game can be taken literally. Due to a bug in the program the NTSC release cannot not be completed. Some of the items you need are hidden under terminals that cannot be searched. This was fixed for the PAL release.

References to the game

The title of the German computer games podcast Stay Forever by former gaming journalists Christian Schmidt and Gunnar Lott is inspired by the synthesized speech "Stay a while...stay forever!" from this game. The voice is also used in the podcast's intro.


On the Commodore 64 version. The game is well known for the use of synthesized speech. Electronic Speech Synthesis (the company that developed the sampled speech for the game) used this game as a test sample.

When this sample was a successful game, Electronic Speech Synthesis (ESS) significantly raised their prices. This caused Epyx to never use their services again (although Impossible Mission II uses ESS, Novotrade developed the game, and they were the same sampled speech tracks used in this game).
