Dark World Dash

A singing doorway takes Kris into the real Stereo Madness.

Play a short solo Deltarune adventure: walk as Kris, talk to Ralsei, and enter a portal into the opening stretch of Geometry Dash’s Stereo Madness. Jump its original spikes and rising platforms to its original song, retry quickly after a miss, and make it home to Ralsei.

Requires your installed copies of DELTARUNE (Chapter 1) and Geometry Dash on Windows. This small native port reads the characters, course, obstacle textures and music directly from your games; none of their content is included in the download. One window, one short course, session-only progress. No multiplayer, full campaign, editor or ship sections.

Controls: arrows/WASD to walk; Z/Enter to talk; Space/Z/Up or left mouse to jump (hold to repeat); R to retry; Escape to pause; M for music.

Original mashup code and dialogue: Dark World Dash contributors, made with OpenAI Codex assistance. MIT; remixes allowed for our original work. DELTARUNE and its characters/music: Toby Fox and the DELTARUNE team. Geometry Dash: RobTop Games. Stereo Madness: ForeverBound. Their content remains theirs and is read only from each player's installed copies. Includes Python, pygame-ce and SDL runtime components with their license notices and credits.
