Yes, if you own Portal and Hollow Knight. Melty is an AI game masher / one-click launcher, not a store that gives you the games.

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.

### Is Melty safe?

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