What players say
@neitantei · loved it · 2026-10-15 · played 4 min: “I really like the unique battle mechanics and the puzzles! My only suggestion is to add health bars to enemies so we can easily see how much HP they have left.”

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@murderdronesholic/deltarune-flowerfall@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 @murderdronesholic/deltarune-flowerfall; 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).
