### What is a mashup?

### Do I need the games?

Yes. Mashups run on games you own. If you are missing one, Melty sends you to its store.

### 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?

Yes, on multiplayer mashups. Press Play to get an invite link, then keep it private, share it, or go public.

### Can I make my own?

Yes. Copy Melty’s instructions into Claude Code or Codex and say what you want. The agent builds it and publishes it.
