A tiny colony needs a way across the forest. Draw living bridges from ants, carry twigs into place and unfold leaves over sheltered gaps. Firm stumps support the route, while hanging leaves bend under the convoy: tie them to forked roots or strengthen the whole span. Find amber caches, adapt to wind, rain and flowing water, and try a different plan whenever a bridge gives way. Explore 300 puzzles across ten woodland environments. Back in the anthill, develop six buildings, research 18 upgrades, collect 36 field notes and discover seven chapters of the colony’s story. Mouse, keyboard and touch controls let you build at your own pace.
Start at the nest. Hold the mouse button or touch a foothold and drag to the next one to extend a connected route. Choose ants, twigs or leaves and keep an eye on your workers and supplies. Stumps are firm; hanging leaves need a root tie or reinforcement along the whole unsupported span. Reach amber caches to collect more materials. Undo or clear your plan freely before a trial. Build the bridge, watch the convoy and return to editing if it fails. The build button changes trial speed. On a keyboard, use 1–3 for materials, Z to undo, Space to build and Escape to pause. Turn a phone sideways to play.
