I just finished playing Cocoon. It was short-but-sweet - it took me two evenings to finish, so probably in the 5-7 hours range - but it was one of the most interesting and engaging puzzle games I've played in a long time. What's especially fascinating to me is that its controls are so simple - everything is done with one analogue stick / WASD and a single interact button - and it's a very linear game, yet it still feels so engaging to play. It's from the lead designer of Limbo and Inside, so it has pedigree.
I played it via Game Pass (ha...) so it's hard for me to say what the value proposition is like. It certainly isn't going to give you the most time for your money, and it doesn't really have much in the way of narrative or themes, at least beyond abstract ones. But it has a gorgeous aesthetic and some fantastic puzzles.
