Description

A surreal and very original game by Geoff Crammond. The game plays out on a 3D landscape with hills and valleys made up of several levels. At the highest vantage point stands The Sentinel, a statue-like being with an energy draining stare, you begin at the lowest. "Energy" plays an important role, there's a constant amount in the game world and each object is worth a certain number of units - including you.
