Stress Free Relaxing Game Recommendations

Yonder is something my wife played. She enjoyed it as it's 100% stress free, but it does get you longing for some combat at times. I don't know much about Littlewood, but it's a game I personally wanna play.

Euro Truck Simulator 2/American Truck Simulator.

Abzu is quite relaxing, and it's only $6.99. That's a very nice number.
Spring Falls is an especially relaxing puzzle game, and it's currently $4.19 [$5.92 with OST, which is a must]. I recently played through that and was quite pleased by my time with it. It's quite lovely and the music is wonderful, too.
Little Inferno is a pretty good game to just chill with. You burn things that react to fire in their own unique ways, and that unlocks other stuff to burn. I really love this one. $3.74 is a stellar price for it.
The dev also makes World of Goo, another relaxing game that costs only $10.04.
A Mortician's Tale is a very laid back and positive look at the death industry. I've only played a little bit of it, but it's a beautiful game so far. I highly recommend getting it with its soundtrack at $3.36.

https://store.steampowered.com/app/351030/Pixel_Puzzles_Ultimate_Jigsaw/ is a very stress-free game, and it is also FTP with purchasable packs that are on sale. I don't know how it plays on Steam Deck, though.

Just got my email to finally purchase my Steam Deck! I'm so excited! I haven't decided for sure which one game I'm going to buy for it this sale yet, but I have a few more days to decide. Thank you all for the recommendations! Two days left on the giveaway!

Spring Falls
Really nice, relaxing little puzzle game.

Eastshade?
Not sure if Steam Deck compatible though.

Spiritfarer - soothing music, great story and is similar to Stardew Valley.

Pick your favorite SimCity and roll with that.

Dear Esther

Audiosurf 2 is an awesome game to relax to after a long day. It has also been updated to work on Steam Deck.
