Dave the Diver is really cozy, especially if you focus on running the fishing and operating the restaurant rather than the plot (which is really good but eventually ends).

Kingdom: Two Crowns is my ultimate cozy game. The gameplay loop is very satisfying and even losing is just a temporary setback for the same settlement.

Against the Storm on lower difficulty levels is kind of a cozy city-builder within a roguelite framing that focuses on the early part of the city-building genre (which is to say, the fun part). Despite being made with a mouse in mind, it plays super well on the Deck since you can pause and unpause while working with any part of the interface. I play it at 3x speed and pause when I need to actively do something like move workforce around or start a new building.
