The Adventure Company has just released a playable demo for Kheops Studio's ECHO: Secrets Of The Lost Cavern. The demo features an intro cutscene that segues into a portion of the beginning of the full game.

ECHO is a point-&-click adventure set in prehistoric times and will have you playing the story of Arok, a young Cro-Magnon man studying the art of cave painting. On his quest to better himself he must learn the world around him and all its mysteries. Along the way he must earn the trust of other men and women and often help them out.

The demo weighs in at 275MB and can be downloaded from 3D Gamers or Gamer's Hell.
