In Sink

Great game, my wife can't describe a square though, would recommend the game. Would not recommend the wife.

This to me is hands down the best puzzle game out there.
Each level (10 in total) offers unique puzzles that you have to complete with a friend where you also need good communication skills because there will be times where you are split and have to tell your partner a piece of the solution.
Had 14 hours of great fun with one of my friends so I recommend this game to everyone liking puzzles and occasionally shouting at your friend.

Oh and also - there is a secret which is always a plus

This game is a great coop escape room puzzler! Also bonus cred for adding new maps when you technically don't have to, since the base game is decent entertainment as it is. I already reinstalled the game twice now for new content.

A solid 10/10 game for us! There's 10 levels I believe, which are about an hour long each. It was perfect because we went through a level each time we wanted to play and it wasn't too long or too short. I got to play this with my partner and we both had a blast. I mistakenly thought this game was something else when we got into it, so I was pleasantly suprised when it turned out to be what is was. Reminds me of the We Were Here series which is one of our favorite co-op series of all time.
I looked at the reviews in the middle of us playing and was concerned at some of the negative ones, especially since it seems a lot of people didn't like the later levels, but we never felt like that. The later levels actually ended up being my favorites. The other criticism I saw was that the symbols get repeated in multiple levels, but that made it easier for us since we had named them already. I was able to communicate which one I was talking about without struggle, saving us a lot of frustration.
I really liked that there were situations where we were seperated and had to use communication to solve a puzzle, but then others where we were both working on the same puzzle right next to each other. It had a good variety of both and felt refreshing as we played.

A charming little game full of properly well-thought puzzles. The co-op experience is flawless; I have not experienced any lag or crashes after playing this game for roughly 20 hours. My only criticisms are that some of the puzzles take too long to retry (for example, when you have to re-type the whole pattern you have already solved just because you haven't been fast enough to push the button - to combat this, there could have been a paste button of sorts), and some puzzles' difficulty were only increased the by making them tediously longer instead of harder to solve.

A well done co-op puzzler experience. Fits right in to the genre with We Were Here and Escape Simulator games. Themes are great and distinguish each level. Minimal issues and not too much frustration. Used external voice chat and generous use of paper and screenshots. Bonus two levels were a nice surprise after completion of the main campaign.
With all puzzles being language-agnostic, almost all of the puzzles require finding, decoding, and communicating symbols/colors/shapes - maybe with an extra relay or two. Some puzzles may not be a hit (trial and error, time-limited, hidden objects) but enjoyed the solves and variety.

In Sink is a solid co-op puzzle game. The puzzles are most certainly fun and it’s always exciting to see what the next level has in store! However, I do recommend taking it a few levels at a time, as the small issues it has may start to annoy with time. Clocking in at around nine hours for our playthrough, it does offer a fair bit of content and will make you feel clever once you figure out each puzzle… though it may be infuriating when you are stuck and the hints are unhelpful. Regardless, grab a friend, hop in, and come up with great ad hoc names for the symbols. Our favourites were ping-pong and fat snake.
