Tri-achnid is a new action/adventure platformer in which you play as a creature of an endangered species of exopod on the verge of extinction. Your goal is to find a safe place for your brothers and sisters, who are tucked away in a portable cocoon, by moving throughout each level using a unique click-drag gameplay mechanic.

Why we picked it: The best platform game decision was a difficult one. While all entries in this category were close, it came down to a decision between Sling and Tri-achnid. Production wise, we've not seen another Flash game that comes close to the level of detail in Sling with its glistening graphics and elastic and pliable physics implementation. However, Tri-achnid ultimately receives our nod due to its atmosphere, unique gameplay and puzzle elements. It's a highly ambitious effort that is both very beautiful and exceptionally creative in its execution. Some people may experience a bit of frustration with its method of control, but persevere and you will be rewarded with an experience that earns Tri-achnid a spot among the Best of 2006.
