Ikonei Island: An Earthlock Adventure - How to Play for Free with Your Friends with the Friends' Pass

The Ikonei Island’s Friends’ Pass allows up to 4 people to play the entire game, with just one bought copy of the game.

Guide to Play for Free with Your Friends

You or one of your Steam friends need to buy a copy of Ikonei Island: an Earthlock Adventure.
The player who owns the game (referred to as “premium player” from now on) has to open the settings menu in-game > multiplayer options > and copy their join code.
The other players then need to select “Join Game” in their main menu screens and paste the code. Done! Up to 3 Friends’ Pass/premium players can join (the multiplayer limit is 4).
As long as the host is a premium player, all the other players will be able to play the game indefinitely for free.
Note: The Friends’ Pass also works as a demo. This means that anyone can install it to play the first ~2 hours for free, solo or in multiplayer. But if they want to continue playing, they must either buy a copy or join the game of a premium player.

Make sure all the players update the game to the latest version. Otherwise, you may experience crashes and bugs.
Check if no firewalls are blocking Ikonei’s access to anything.
Set up the time correctly on all players’ PCs.
Make sure everyone’s graphics card drivers are up to date.
Make sure everyone has enough storage space (Ikonei requires ~6 GB of free space).
