## What "Hollow Knight + Outer Wilds" means here

Use Claude Code or Codex with Melty instructions if you want a custom Hollow Knight / Outer Wilds variant. The agent builds it; Melty scans the upload and lets friends join from a link.

Hollow Knight is Metroidvania. 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 Hollow Knight / Outer Wilds files back.
