A bible-based adventure game - from darkness to light! Nacah is a Bible-based point and click adventure game. The perspective is first-person and the navigation is slide show, similar to Myst. The player character is stranded on a group of islands and the point of the game is to find a way to leave them. Otherwise, the game has no plot. There are a few mechanical puzzles, but most of them are Bible based, and having a Bible handy is recommended in solving this adventure.
