Not much is known about the early production of Little Space Heroes. There apparently was an option for mailing, and there was no option to summon pets or use your Jetpack or Bubble Blaster. Coins were in the top right instead of the top left, and there was a TV-like robot in the bottom left corner, and the moderator symbol was in the bottom right corner instead of the top right corner. Bubble Blasters had a different command because the button for it was not introduced yet. There also was no Map, suggesting players possibly had to walk everywhere, or used something else.
