The Sentinel is a classic action-strategy game by Geoff Crammond.

Avoid the deadly gaze of the Sentinel. Traverse a surreal, procedurally generated checkerboard landscape. Absorb energy from trees, boulders, and enemies. Create clones of yourself to teleport into. Gain the high ground and absorb the Sentinel itself to move on to the next of many levels.

Cheat codes are available.
