What "Portal 2 + Outer Wilds" means here
Co-op chambers and gels that Melty can join to other owned Valve or puzzle games. A short exploration loop that mashups can join to other owned puzzle or space games. Together they are the Portal 2 + Outer Wilds mashup slot.
Melty does not need a celebrity mashup name for this query. Portal 2 + Outer Wilds is two owned games and one Play button.
Portal 2 is puzzle. Outer Wilds is exploration. Melty starts the mashup on Windows. Uninstall restores files. Multiplayer mashups mint an invite link.
Play, friends, AI
Press Play. Melty downloads the mashup, installs files, and starts the host. Uninstall puts Portal 2 / Outer Wilds files back.

What does Play do?
It downloads the mashup, installs what it needs, and starts the game. Uninstalling puts every file back as it was.
Can I play with friends?

Is Melty safe?
Every upload is checked for dangerous files. If a mashup looks wrong, report it from its page.
