Join up with an online friend and escape the island together!

NOTE: This game is co-op only. It requires 2 players to have a computer, internet, and voice communication. We recommend using something like Steam's voice chat, Discord, or if want you could both join a two-person group in our Discord: Discord.com.



In the full game you follow the journey of two friends shipwrecked on a mysterious island. Travel through rifts to other worlds where you'll have to solve a series of differently themed escape rooms, puzzles, and other mysteries. Each thematic rift you conquer brings you one step closer to getting back home - so success is reliant on you and your partner being In Sink.
