Somewhere early 1996, game's development was outsourced to a company called Toy Pops which closed its doors 3 months after the beginning of this project. A prototype version, at an alpha stage of production, surfaced in 2016 on the internet.
During development, the game was titled 'DarkSeed'. Another name, Dragon's Heaven, was given to the game tentatively since it was difficult to get the trademark for DarkSeed.
The game code has some similarities with the "Choujin Gakuen Gowcaizer [Model NGM-094]
" one. The game init code routines are identical.
