Sporefall

You begin as a single spore in the soil. Tap to gather nutrients and your cord grows toward the nearest glowing tree. Every tree that joins the network gives you a gift and an evolution point, and there are more skills than points, so each colony walks its own path: decomposer, networker or symbiont.

When growth slows, release spores. You lose the nutrients and start a new colony, but every spore makes all growth faster, and your forest, cords and skills stay.

The browser version is the demo: the first trees are listening. The full game connects all twelve, including the mother oak, in about thirty minutes start to finish, and the fastest forests go on the leaderboard.
