MoonLite

A free social sandbox set in a low-poly night park. Mix your own music stems live for everyone standing nearby, host a cinema screening, race karts, play pinball, or read a book another player wrote. No score, no enemies, no fail state. Best with headphones on.

This is the same build as the Steam version. Steam adds automatic updates and the optional supporter purchases — otherwise it's identical, and the game is free either way.
