Heiankyo Alien is a Game Boy puzzle game from Meldac built around maze-style alien trapping gameplay. This portable version includes both the original-style Old Version and a redesigned New Version with an expanded layout and competitive play.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Educational/puzzle gameplay centers on navigating maze layouts and dealing with alien threats through positioning and timing.
• Old Version preserves the original Heiankyo Alien format with its classic depth and straightforward maze challenge.
• New Version reworks the concept with a larger layout designed specifically for this Game Boy release.
• A versus mode allows opponents to play against each other, adding a competitive option beyond the solo puzzle format.

The title connects early arcade-style maze strategy with a handheld redesign made for the Game Boy Compact Video Game System. Its dual-version setup gives the cartridge a clear distinction from a simple straight port.
