In a 1988 interview with the game's manager Kouji Hiroshita published in GSLA, he stated that the first stage they made was the fifth stage, Revenge of Moai, because the Moai were a mainstay in the series and their character design had already been established. The thought for that stage was to stuff it with as many Moai as possible.

After that, they created the first stage, Artificial Sun. The purpose of the stage was to give the player have a chance to power up, but they thought if the player was given a bunch of power-ups, it would be boring. They wanted something where expert players could gain power-ups easily, and where the more players tried to power-up, the more changeling the enemy attacks would become.
