Absorb energy from the landscape
Trees serve as the basic unit of energy. Absorb them from the scenery when you're able to do so. You can only assimilate objects if the square upon which they rest is visible to you.
Gain altitude
Stack boulders, place a "synthoid" on top and teleport your consciousness into this new vessel. Reabsorb the shell and any boulders you left behind. Boulders are worth 2 energy units, a synthoid, 3.
Elude the Sentinel's watchful eye
When you find yourself caught in the Sentinel's gaze, it will leach away your life-force, scattering it across the terrain in the form of newborn trees. Move before it drains and kills you. Alternatively, hyperspace to a random location at the cost of 3 energy units and leaving your old vessel and any boulders behind.
Take the throne
When you have absorbed enough energy and gained enough altitude, absorb the Sentinel, claim its throne on the pinnacle and advance to the next world that awaits.
The Sentinel is not alone
As your voyage takes you into more challenging worlds, you'll have to grapple with additional sentries. Equally formidable as the Sentinel, they rotate in the reverse direction. Maintain a watchful eye on them and strategise your approach accordingly.

Originally released in 1986 by Geoff Crammond, The Sentinel, also known as The Sentry in the United States, was a pioneer in 3D graphics for home computers. It quickly became one of the highest rated games on the BBC Micro, ZX Spectrum and Commodore 64.
In the annals of video game history, certain titles stand out for their innovative gameplay, groundbreaking graphics, or compelling narratives. Among these is the 1986 game "The Sentinel", published as "The Senty" in the USA.
Developed by Geoff Crammond, a British game designer renowned for his work on the Grand Prix series, The Sentinel pushed the boundaries of what was possible on home computers at the time, offering a unique blend of strategy, atmosphere and tension that captivated players and critics alike.
For its time, The Sentinel was a revolutionary game. It was one of the first games to use solid 3D polygon graphics on home computers, a significant leap forward in an era when most games were text based, using 2D sprites.
Geoff developed a technique where rather than rendering a complete view in real time - impossible on 8-bit hardware - the camera would rotate a number of degrees at set intervals. The edge portion of the screen would be rendered as it came into view.
This mechanic was built into the game play and for the first time on home computers allowed for a truly immersive 3D gaming experience.
