In Sink: A Co-Op Escape Prologue is the free first level of a two-player online co-op escape game. You and a partner are shipwrecked on a desert island, and the puzzles are split so each player sees half of the information, forcing you to describe shapes, symbols, colours and numbers to one another. It suits pairs who want to try a talk-it-out co-op puzzler before buying the full game.
The prologue holds a Very Positive rating from over 1,700 Steam reviews. The one detailed review praises how communication matters as much as logic, with wheels, levers, pressure plates and visual clues that only make sense once both players share what they see. Puzzles avoid written instructions, are designed to be colour-blind friendly, and a hint system nudges without spoiling. Another player found it confusing at first before it clicked.
As a demo, it is short, with a median playtime of about an hour, and a second level is gated behind joining the developer's Discord. Written reviews are few, so detail on difficulty is limited. Since it is free, it is an easy way for two friends to see if the full game suits them.
Pros
- Free, with puzzles split so each player holds half the clues
- Language-free, colour-blind friendly puzzle design
- Hint system helps without giving solutions away
Cons
- Only one level, around an hour long
- Second level requires joining the developer's Discord
- Online co-op only; needs a partner
