A tribute, written in one file.

Dungeon Prince is an original, non-commercial fan tribute to the 1989 cinematic platformer that defined a genre — the running leap, the automatic ledge grab, the rhythmic sword duel. None of the original code, art, or audio was used or extracted; every pixel and every clang was rebuilt from scratch for the modern web.

The goal was simple: capture the feel — the weight of a fall, the terror of a spike pit, the calm of a torchlit corridor — using nothing but a canvas, an audio context, and a text file of tiles.

Every brick, torch flame, portcullis and figure is drawn procedurally on a<canvas>each frame. Every clang, footfall, and fanfare is synthesized live with the WebAudio API. The whole game is a single self-contained script — no build step, no assets, no dependencies.

Physics run on a fixed timestep tuned to the classic cinematic-platformer canon: standing and running jumps, ledge snapping, fall damage measured in floor-heights, and swordplay built entirely on telegraphs and timing windows.

The site around the game is a TanStack Start app on Lovable Cloud — file-based routing, SSR by default, deployed to a serverless edge worker. The game itself is a static PWA bundle under /gamewith its own manifest and service worker, so once you install it, it launches offline.

No ads. No tracking. No accounts. No paywall. The source is on GitHub under a permissive license — clone it, fork it, ship your own episodes. If you build something with it, tell us.
