Disc Duel

A 1v1 disc-throwing duel in a neon arena with 9 m glass walls. Discs ricochet off every wall, floor and ceiling; each bounce before a hit adds damage. Nobody has a health bar: deal more damage than your opponent before the 90-second clock runs out.

Maps

Pick the map on the menu. Online, the host's map is used.

• Classic: a 22 × 32 m rectangle.
• Plus: a plus-shaped arena, 14 m wide arms and 58 m tip to tip. Discs can't pass the glass corners, so they're cover; bank shots (and the CPU) reach around them.

Modes

• vs CPU with Easy, Normal and Hard difficulty. Both fighters take the difficulty's build: broad on Easy, athletic on Normal, tall and slim on Hard, with a hitbox that matches (smaller on harder levels). Online matches use the Hard build.
• Online 1v1. One player clicks Create match and sends the 4-character code; the other clicks Join. Browsers connect directly with WebRTC via PeerJS. Some strict networks (work, school, mobile) block direct connections.

The glass walls look out on a stadium of other arenas. On the GitHub Pages site, other players' live matches (online or vs CPU) appear in the neighbouring cubes; cubes without a real match run CPU exhibitions. Add ?stadium=0 to the URL to turn the exhibitions off.

Stadium hub: stadium-hub/ is a Cloudflare Worker (deploy with npx wrangler deploy from that folder) that assigns cubes, relays match digests and stores the worldwide leaderboard. See docs/stadium-design.md for the plan to show real online matches there.

Names, stats and leaderboard

• Set your name on the menu; online, your rival sees it.
• After each round, the results screen compares both players: damage, hits, accuracy, damage per hit, best hit, bank shots, most bounces in one hit, shield reflects, and curve, Heavy and Split hits.
• The leaderboard ranks the best rounds by damage for each mode (Easy, Normal, Hard, Online). On the GitHub Pages site it is worldwide (stored on the stadium hub; each player appears once per mode with their best round), with a This computer view too; inside the claude.ai artifact it is shared with everyone who can open the page.

Controls

Default keys; every key can be changed in Settings & controls.

Input	Action
Mouse	Aim (click the arena to capture the cursor). The crosshair turns orange on your opponent
Hold left click	Wind up, release to throw. A tap throws at 37.5 m/s, a full 0.8 s wind-up at 57.5 m/s. Getting hit doesn't cancel a wind-up: you're slowed for a moment instead
Flick the mouse as you release	Curves the throw that way; most of the spin is lost at the first wall
Left click (disc in flight)	Recall the disc
Right click / Q	Shield, reflects a disc back at its thrower (disc must be in hand)
W A S D	Move
Space	Jump; in the air next to a wall, wall jump
Left Shift	Dash; once more in the air, holding your height
C	Slide, ducking under high discs
E / R	Arm a Heavy / Split disc for your next throw
V	Switch between first person (default) and over-the-shoulder view
M / Esc	Mute / Pause

Special discs

Heavy recharges for 9 s after use, Split for 7 s.

• Heavy (E): about 28% slower and much bigger, +10 damage, and a shield can't reflect it.
• Split (R): at its first wall bounce it throws off two shards that live about 1.3 s and hit for 8 each.

Settings

• Mouse sensitivity as a multiplier or in cm/360° (enter your mouse DPI). The game asks for raw mouse input, so cm/360° is exact in Chrome and Edge.
• Field of view (horizontal, first person) and effects volume.
• Graphics: neon glow on/off, floor reflections on/off, ambient occlusion (soft shading where things meet; off by default), matches in the neighboring arenas on/off, and a Fast resolution for slower computers (it also drops the fighters' shadows and the shading).
• Show frame rate: frames per second, frame times and, where the browser allows it, how long the graphics card takes per frame.

Look

Discs leave glowing light trails. Every bounce throws sparks, flashes light onto the walls and floor, and sends a ripple of light through the arena's grid, while pulses of light run along the grid lines; a hit bursts a shockwave off the fighter.

Sound

Sounds are positioned in 3D (HRTF), so with headphones you can hear which wall a disc bounced off and where a disc in flight is.

Scoring

Direct hit 12 · each bank +8 · reflect +10 · recall hit 10 · a full wind-up adds up to +10.
