With this game, Technos Japan developers pushed even further the peculiar gameplay elements on which "Eggs" and "Scrambled Egg" were based, by putting them into an Indy-themed, multi-room mayhem.


The subtitle is slightly different between the new and old versions. The new version says 'Dr. John's Adventure' while the old version says 'Dr. Kick In Adventure'.


By hitting the lonely idol statue in the opening screen with a headbonk, a secret message will be displayed: 'A short cut to a treasure room. Go into an upper or a lower entrance. And... Go on left!'. This obviously refers to the game map. As a side note, the older version of the game displays the same message in Japanese katakana characters, an eloquent proof that the older Mysterious Stones set was meant for use in Japan only.
