About Mosa Lina
Mosa Lina is an adventure‑indie simulation that rejects the “lock‑and‑key” design of many immersive sims. Hand‑crafted levels are presented in a random order, so each playthrough offers a unique sequence of puzzles and tools.
The game features physics‑driven puzzle‑platforming, local and online co‑op, a built‑in level editor, and Steam Workshop support. It runs on Windows, macOS and Linux.
01 / THE GUIDE
Randomized Level Selection
Each session draws from a pool of handmade levels that are shuffled randomly, meaning the order of levels differs between runs. The developer notes it is impossible to verify every tool works on every level, emphasizing unpredictability.
Only a fraction of the total levels appear in any single playthrough, so players may finish without encountering many designs. This randomness is presented as the core source of the game’s challenge.
- Accept that the same item may appear repeatedly; adapt your approach each time.
- Focus on the current tools rather than anticipating future ones.
02 / THE GUIDE
Physics‑Driven Puzzle Platforming
The player, tiles, items and obstacles all share a single physics engine, allowing any object to interact with any other. This design enables emergent solutions that are not scripted in advance.
Collecting fruits to open the portal is the stated goal, but the method is entirely up to the player, showcasing how the physics system supports creative expression.
- Observe how objects bounce, roll or stack; unconventional uses can open shortcuts.
- Experiment with combining multiple items to produce compound effects.

Local & Online Multiplayer
Mosa Lina supports couch co‑op, online play, LAN and split‑screen, letting friends tackle puzzles together regardless of distance. The description highlights the potential for “crazy plays, hilarious fails and all‑around creativity.”
Whether playing on the couch or online, Mosa Lina can be enjoyed together, opening up possibilities for creative and unpredictable plays.
- Communicate tool locations with your partner to avoid duplicated effort.
- Use split‑screen to keep both players’ actions visible at once.

Level Editor & Steam Workshop
A built‑in editor lets players design custom level packs, which can be shared via the Steam Workshop. Community‑made packs provide extra challenges for those who have mastered the base game.
The description encourages checking out community packs as a way to extend play after completing the core experience.
- Start with simple layouts before adding complex physics interactions.
- Test your level in both solo and co‑op modes to ensure versatility.
