Primordia is a point-and-click adventure game that combines the challenge and depth of the classics with a streamlined interface and a player-friendly design: puzzles emphasize logical thinking and exploration, rather than trial and error or endless backtracking. The game features over fifty hand-drawn rooms to explore, dozens of distinctive characters and complex machines to interact with, and gorgeous painted cutscenes to soak in. And, as some might note, it features a sarcastic floating sidekick named Crispin
