Build. Pop. Repeat.
Spend cash on towers beside the track, then send the next wave. Add camo detection before round 24 and lead damage before round 28. Popped layers pay for upgrades. Select a placed tower to choose upgrades along two of its three paths, or sell it for 70% of your investment. This build supports dart tiers 1–3 and tiers 1–2 for the other towers.

They have layers.
Balloons shed layers and split into children. Black resists bombs, white resists ice, and lead resists sharp shots. Camo needs detection; regrow recovers layers. Try all 17 types and fortified variants in the sandbox.
Handwritten assembly.
Movement, targeting, damage, cash and placement run inside a Wasm module assembled from readable WAT source. Canvas draws the results. No account, no install, no server simulation.
