You are one of—as the author calls it—an "endangered species of exopod on the verge of extinction." It is your goal to find a safe place for your brothers and sisters, who are tucked away in a portable cocoon. You learn in the introductory cut-scene that your parents are killed, and that you alone must save your siblings. So you carry this egg sack around through the various levels on your quest for your species' survival.
Your protagonist is a three-legged arachnid-esque creature. Movement is controlled by moving the three feet through clicking and dragging. You may also use WASD keys to position the Triachnid's head for balancing. Like any self-respecting wall-crawler, your feet can attach to almost every surface.
This even includes your egg-sack, which you can carry around the levels in your mouth. If you get hurt by falling rocks, menacing enemies, or by hurting your limbs on sharp edges, you can get back to full health by catching some of the smaller insect-like by-fliers, and (surprise surprise!) eating them!
How do spiders catch flies?
In their web of deceit, of course! Naturally, you can construct your own webs, and use them just like any ordinary spider. You can attach them to walls, you can sit on them, you can cut them off again, and you can just watch potential prey getting caught in them. Using just a single thread, you can descend from one platform to another, as later levels require you to.
Analysis: The graphics are simple, yet appealing, the music enhances the atmosphere perfectly. Controlling all aspects of your beloved exopod might seem overwhelming at first, but the game introduces them quite gently during the first few levels.
Just to apply a little bit of criticism, the only feature that the game is lacking would be a save feature.
All in all, Tri-achnid is a very fresh and original title, well-designed by Florian Himsl and Edmund McMillen, both of whom have found their way into the right-click context menu of the flash application.
