The "Ultimate Edition" tag typically refers to the full commercial release on platforms like Steam and the Nintendo Switch , which includes several enhancements over early versions:

: A complete set of retro-styled metal tracks by Andrew Hulshult.

: Built-in tools for creating and sharing custom map packs via the Steam Workshop .

: A 30-level story that serves as a prequel, detailing the strange events in the town of Dusk before the main game begins.
