Hi there,

according to the GOG shop comments and any other site in the internet, this game has multiplayer.
But I can´t find the + button to play with my friend?

Edit: NO multiplayer in the GOG release...

Thanks for editing! We don't need to ask the same question anymore. :'(

knolle told OP that the version on GOG is single player only.
