What players say
@yzykyl · loved it · 2026-10-30 · played 12 min: “I tried all characters and they fight great and are nicely unique to each other. I do think goblin swarm needs to be more punishing since it's pretty easy to dodge unless you can lure them under the platform. Curious if I can beat other players!”
@neitantei · loved it · 2026-10-30 · played 15 min: “Fun game! The Hunter feels a bit op imo. Looking forward to seeing more characters and crossovers!”
@larrielabs · loved it · 2026-10-30 · played 5 min: “ヾ(•ω•`)o I love the character designs, especially their unique abilities! 🦇✨ The different attacks make the fights fun to play! Tho, I noticed that my opponent often gets stuck and can't jump over obstacles. 😅”
- @larrielabs replied 2026-10-30: “That aside, I'm excited to see more characters added in the future and discover what other abilities they might have! 💕 ~”

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@sandyone/blood-moon-duel@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.
The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @sandyone/blood-moon-duel; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).
