"Originally, there was a group of antagonists for the game simply called "The Stars of Takamatakame." Although there's almost nothing left in the programming because they were barely worked on. The boss of Area 4-2, simply called Haumea, only remains. There's concept art of Haumea.

The names of the 9 bosses are also still available. In order of appearance, they would be:

Makemake (1-1), Orcus (1-2), Quaoar (2-1), Eris (2-2), Pluto and Charon (3-1), Sedna (3-2), Gonggong (4-1), Haumea (4-2), Ceres (final boss).

Wouldn't it be great to see them again someday? :D"
