Having to make my brain work together with my girlfriend's brain to haphazardly paint a shared mental picture of an OC DONUT STEAL weird logic switch puzzle the devs made up might have been cute and interesting once, twice, maybe three times, but this is simply not something you should be making the player do over and over and over in all your games it seriously does NOT carry the game for you guys.

Okay, imagine you are placed in solitary confinement and given a Rubik's Cube but you've never seen a Rubik's Cube once in your life. You don't know it's a puzzle that can be solved, you don't know what the solved state looks like, you don't know every row can be rotated on both axis, you don't know that all sides can be made to be one uniform color. You're not allowed to leave your imprisonment until you solve this cube you know nothing about. Now imagine that you also only have one half of the Rubik's Cube and someone locked in a different room has the other half of it and all you two have is a radio to communicate. You both have to work together to solve the Rubik's Cube, without knowing what it even is or being able to see the other person's half.
And then you know when you are working on a Rubik's Cube and you turned like 7 out of the 9 squares on one side Yellow? So close but you ultimately have to mess the surface up and start moving everything around again and make it less orderly before you can get close to the solution again? Imagine that frustration but in co-op, where half the surface is split away and in your partner's hands so you have to verbally communicate back and forth for several minutes to realize you're in an "almost solved but not really" state, and then you BOTH have to frustratingly undo the progress to find the real solution.

This is how the majority of the puzzles work in We Were Here and honestly, it's just not fun. There's no real life applications for the skillsets being demanded of the players, it's a completely unergonomic, anti-human game design. Einstein and Feynman weren't in separate cities when they cracked the atom, and if they would have been, they wouldn't have been prevented from sending eachother pictures or other varied information.
Presenting esoteric, random puzzles that are split between two people who then must communicate the nonsense between eachother until the two people's brains can together paint some semblance of a full picture is simply not a fun or ergonomic or sensible activity it's a complete chore.

The devs need to go back to the drawing board if they intend to continue this franchise because this is just getting too much. The puzzles where you have to describe weird shapes to eachother and come up with things like "this symbol looks like Shrek, press the Shrek button" are cute and fun. Puzzles where both players can see the puzzle are way better, too. There's puzzles that have one player doing most of the work - these are a little boring but even they can stay.

Again, though, the "Rubik's Cube split between two isolated players" style needs to be finished or relegated to "Final Boss Puzzle" because they're not fun in the least. I'm not an Eldritch creature training to ascend as an Outer God, give me human puzzles that feel good to do. If they insist on keeping these around, they need to expand players' tools. Give us picture-in-picture view of the other player, or the ability to draw and send the drawings to the other player. I'm sick of describing one half of a complicated logic-switch puzzle with made-up alphabets to my girlfriend who then must describe her half back to me.
