Enjoy a colony simulator without the steep learning curve. Simply place resources, sit back, and observe.
The Teno are a volatile alien species, capable of fusing intelligently with their environment, or exploding into a pile of bones. As you learn about them, you use this information to grow their colony, unlocking new resources and uncovering more advanced behaviours.

Investigate the extent of the aliens' intelligence, and find ways to make use of their volatility.

Enjoy a hand-crafted retro pixel art aesthetic, a lo-fi sci-fi soundtrack, and tonnes of weird little guys.
