10oct2016 update includes fixes and upgraded scenes.
AdaVenture is a kid-friendly retro point&click game, intended to be a minimal extension to 3D of the original 2D Atari game named "Adventure", but with a few artistic liberties taken.
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. It was recently stolen by a surly foe named King Leonidas of Sparta.
Your quest is to find and return the royal chalice to its pedestal within the castle of Xerxes...a stealth mission to avoid a bloody confrontation. But, there will be obstacles to overcome. You must find the keys to various realms, defend yourself against dragons, avoid pesky bats who steal things only to drop them in random locations, and survive the snake-ridden maze.
For Mac OS-X and GNU-Linux.
