AdaVenture is a kid-friendly retro point & click game, essentially intended to be a minimal extension to 3D of the original 2D Atari game named "Adventure". Now runs on Windows, OSX, and GNU/Linux. Set in ancient Persia, it begins outside the castle of the young King Xerxes, who inherited a golden chalice from his father, Darius the Great. Coveted by Greek foes King Leonidas of Sparta and King Minos of Crete, the chalice has been stolen. Your quest is to seek and return the royal chalice to its pedestal within the castle of Xerxes...a stealth mission to avoid open hostilities. But, there will be obstacles to overcome. You must find the keys to various realms, defend yourself against dragons and the Minotaur, avoid snakes and pesky bats who steal things only to drop them in random locations, and survive the maze of the green mamba.
