There exists 5 versions of Donkey Kong 5: The Journey of Over Time and Space:

• The original version featuring Donkey Kong
• Harry Boy and the Chamber of Secrets, featuring characters from Harry Potter
• 2003 Digitmon Sapphire featuring Digimon and Bubble Bobble characters
• Super Marrio Sunshine, which is identical to Over Time and Space aside from a different title screen and an added glitch, still featuring Donkey Kong and not Mario
• Digit Dinosaur 7: The Adventrue of Devildom which is identical to Digitmon aside from a different title screen, and is theorized to predate it due to having Sintax's copyright info.

Of the 3 main releases, the level layouts are closest to Super Mario Bros. in Digitmon, and least accurate in Harry Boy.
