🌊 CHANNEL [1]
Critters slurp into the trough and ride it downstream. Connect channels
into networks — flow auto-orients toward the nearest colony.
🧱 DAM [2]
A wall that blocks critters and tide. They slide along it rather than
crossing. Useful to redirect critters away from danger.
⚙️ PUMP [3]
Bounces critters straight toward the nearest colony, not just along the
channel. Strong impulse on first entry. Place near danger to fling
survivors to safety.
🔀 GATE [4]
Velocity booster — one-shot kick along the network's flow direction
when a critter enters. Place gates along a channel to accelerate critters
downstream.
🏛 COLONY [6]
Hatchery + shelter. Earns credits/sec. Critters near a colony are
partially shielded from death. Upgrade at the shop for stronger
protection & visible fortifications.
❌ REMOVE [5]
Clear a placed voxel. Use to redesign your network or remove a colony
that's about to be destroyed.
