Woodyn is a multiplayer woodland survival game. You control a tree β eat nutrients scattered across the forest floor to gain rings and mass, then absorb smaller trees to become the dominant force in the forest. The map is shared with other trees (players or bots), and only the largest survive.
Think of it as a living forest ecosystem: you expand, decay, split, and compete β shaped by terrain, powerups, and the decisions of every other tree on the map.
Your tree is measured in rings β visible as concentric circles. More rings means a larger radius, more mass, and more power. Your current mass (rings Γ 100) is shown in the top-left corner.
Trees can eat each other. To absorb another tree, your cell must be at least 10% larger than theirs and physically overlap. The smaller tree is absorbed and adds mass to your tree.
Press Space to split your tree in two, launching half of your mass toward your cursor at high speed. This is your primary offensive tool β a well-timed split lets you close the gap on prey that's just out of reach.
Powerups appear as glowing symbols on the map. Drive through one to collect it. Each has a limited duration and respawns after a cooldown once collected.
| Scenario | Result |
|---|---|
| Both trees have Mirrorwood | The smaller tree wins β both mirrors flip the advantage toward the smaller holder. |
| Thornburst vs Mirrorwood | Thornburst wins unconditionally β it's checked first. The Mirrorwood holder gets split regardless. |
| Kill a boosted tree | You inherit their remaining speed boost if it outlasts yours. |
| Enter a warp while split | Not allowed β you must be a single cell to use a hollow log portal. |
| Thornburst while larger | Thornburst only fires when you're the smaller tree. Being larger deactivates it. |
Two leaderboards track your best performances each week. Top Foresters ranks players by their peak mass β how large you managed to get in a single life. Top Hunters ranks players by their best kill streak β how many consecutive kills you landed before dying. Both boards are shown on the start screen and after death. They reset every Sunday at midnight. Since there are no accounts, names aren't verified β it's the honour system, like an arcade high score table.
If you stop moving or interacting for too long, you'll be returned to the start screen automatically. After being harvested, you can spectate your killer for a short time β you'll be prompted to keep watching or return to the menu. The forest only comes alive when players are present β when everyone leaves, the bots rest too. Jump back in any time to wake the forest.
