Babel no Tou

Babel no Tou, or The Tower of Babel, is a Japanese exclusive puzzle platformer from Namco for the Famicom (NES), released in 1986.

You control the archaeologist Indy Borgnine, who climbs the Tower of Babel to find the Hanging Gardens. On each floor you have to move L-shaped blocks to build a path to the exit, while avoiding enemies.

The game is in Japanese, but the puzzles are easy to understand.
