About Daemonaut
A free side-scrolling action game for the browser. The entrant's pitch: “Teenager Leon fights through Daemon-filled mindscapes to wake up from his coma.” The game's code has attack, dash, parry and jump actions, health bars for daemons and bosses, and on-screen touch buttons for phones, which must be held in landscape. The developer, George Longovitis, names the retro game The King of Dragons and the retro-style game Blasphemous as inspirations and says the game comes from a film idea of many years; the developer made it alone in 10 days. The in-game credits read “Made 100% with ♥ & Claude by George Longovitis” and list the assets separately: visuals generated with Grok, sound effects from Freesound and music from Suno, edited with Audacity and 123apps; the game is built with Three.js and Vite. It was made for the Cursor Vibe Jam 2026, whose rules required at least 90% of each game's code to be written by AI; the official submission lists Claude Code as the tool. It finished 686th of 945 entries. Free in the browser on the developer's own domain.
How it was built
Partially verifiedIn the official Vibe Jam 2026 submission the entrant lists Claude Code as the tool and answers Yes to the AI-written field; the jam inspiration mentions “Claude's ability to help us create anything faster and simpler than ever”. The in-game credits read “Made 100% with ♥ & Claude by George Longovitis”. No devlog describes how Claude Code was used. The credits name other sources for the assets: visuals generated with Grok, sound effects from Freesound and music from Suno.

“Made 100% with ♥ & Claude by George Longovitis”Verification notes: Tool (Claude Code), engine (ThreeJS), genre (Action, Adventure, Platformer, Retro), pitch, inspiration and the multiplayer (No), mobile (Yes) and portal (Yes) flags from the entrant's answers in the official Vibe Jam 2026 games data (submitted 30 Apr 2026, 21:58 UTC; final rank 686 of 945 entries, no award), re-read on 5 Nov 2026; rule 3 on the jam page requires at least 90% AI-written code. The credits line “Made 100% with ♥ & Claude” does not say what share of the code AI wrote, so no AI code share is recorded. Team size and the 10-day build time come from the entrant's inspiration answer (“this was done solo in 10 days”).
