 The game underwent a beta location testing in January 1990, and this early version of the game featured longer stages that were deemed not suitable for arcade play and as such, the developer scaled down the levels but some were cut in the final version.It was the first title developed by Alpha Denshi for the Neo Geo platform and featured graphical effects such as zooming and rotation.There were originally 27 planned transformations that players could morph into, but only six were finalized due to gameplay changes during development.
