Second game mode selectable at dog select (host-authoritative online): - js/sim_arena.js: top-down sim, same export surface as sim.js — x/y plane plus a z hop axis (Space / comma); KOs by knocking dogs into abyss pits - js/mapgen_arena.js: mirrored symmetric arenas — walls, pits, center clearing, guaranteed spawn-to-center corridors, crystals/spikes/launch pads, mirrored saw pairs; fallback pit pair since pits are the only KO mechanic - specials re-imagined per dog: zoom dash, ram + hop-slam, zip-leash slingshot, blink, hover (floats over pits/saws/spikes) - render: arena tiles with wall shadows + void pits, top-down dog drawing with z-lift over a ground shadow; new fall event/sfx - B.HOP input bit so 'up' can mean north in top-down (Space also jumps in side view); mode toggle UI + mode carried in start/rematch net messages Tested: arena mapgen determinism/symmetry/connectivity + chaotic matches + pit/hop scenarios headless; local chaos + full P2P arena match (host mode flip syncs to client) in two headless browsers with zero page errors.
