Space Janitor

Space Janitor is a game built for the js13kGames competition — and the title tells you exactly what tone to expect. Rather than casting you as a space marine or a heroic pilot, it puts you in the boots of the person who has to clean up the mess. It is a refreshing subversion of the space-game formula, and that comedic premise gives the game a personality that pure-action jam entries often lack.

The 13-kilobyte constraint forces the same discipline every js13k entry faces: no room for bloated systems, decorative assets, or hand-holding tutorials. What survives the compression budget is the core mechanic and the charm. The source code is fully open on GitHub, which makes it a useful reference for anyone studying how to build a complete game experience inside the size limit.

It earned top-tier recognition in its competition year. If you enjoy games that lead with character and concept over raw spectacle, Space Janitor is the kind of jam entry worth your fifteen minutes — small, self-aware, and built around a single good idea executed honestly.

Space Janitor's controls are displayed on the in-game title screen. As with most js13k entries, expect keyboard or mouse inputs — arrow keys or WASD for movement, and a primary action key for the cleaning/interaction mechanic.

The specific objective varies with the game's design, but the janitor premise suggests a task-completion loop rather than pure combat: figure out what needs cleaning, navigate to it, and deal with obstacles (space debris, zero-gravity physics, or wandering hazards) along the way. Approach it as a puzzle-action hybrid rather than a shooter.
