Stress Free Relaxing Game Recommendations

I don't know if they work on the Steam Deck.
A Short Hike
ABZU
AER Memories of Old
Grow Home - I thought this was relaxing and stress free, but I can see how some people might find the difficult platforming stressful.

Do you want us to choose between the two you've mentioned or do you want other recommendations as well?

Coloring Pixels. The base game is free and then they have like 20 to 30 DLC packs for $1 each.

I love this type of games, i reccomend animal crossing but unfortunately isn't available on steam 😥 but if you use an emulator you can play it

Spiritfarer is amazing and on sale for $10 right now ^_^

*Edit; they have a demo too, try it out!

I found Cozy Grove to be quite a chill game on Switch.

Many minimalist puzzles with chill music.They aren't really for long-term, but they are very good as breaks between bigger games.

Here are my two stress free game experienced

I was gonna recommend Stardew Valley and My Time at Portia, but then I read the whole thing. Yonder: The Cloud Catcher Chronicles quite nice too.
I started Cat Quest recently, it's different from the ones you list, but you could try it. There's also My Time at Sandrock, it should fit what you are looking for.
These are from my wishlist (so haven't played them), but might be worth checking out

• Craftopia
• Core Keeper
• Pilgrims
• Stranded Sails - Explorers of the Cursed Islands
• Atomicrops (probably not relaxing type)
• Banished (I doubt this would be playable on Steam Deck though, there's too much UI)
• Graveyard Keeper
• UnderMine
• Parkasaurus
• The Gardens Between
• Crashlands
• Settlement Survival
• Little Witch in the Woods
• Mineko's Night Market (not released yet)
• Roots of Pacha (not released yet)

These, from by WL, are very different genre imo, in case you are open to them:

• Potion Craft: Alchemist Simulator
• Röki
• Carto
• Tower Unite
• The Wild at Heart
• Lumino City
• Beacon Pines (not released yet)

Hope that was helpful.

Littlewood sounds very relaxing

Cat Goes Fishing can be played very relaxed.

I don't have a steam deck so check before but here are some ideas that seem to fit
Apico
Omno
Raft

Some of my favorite chill games:
ABZU
AER Memories of Old
Grow Home / Grow Up
InnerSpace (It has mixed reviews so YMMV but I thought it was a charming little game)
Journey
Paper Beast (I loved this one)
Townscaper (Less a game and more a sandbox to play in, only recommended if you like building stuff)
Splice (Sadly not on sale right now but it isn't too expensive)

I am virtually running circles around Strange Horticulture, it really does seem like it would fit in there and to me looks absolutely lovely.
And maybe Slime Rancher, it is definitely cute 😄
I do enjoy Graveyard Keeper, too, but it is a bit of a grindy one and might not be everybody's kind of humour.

Littlewood is so good.

Other options:
Starbound
Core Keeper
Moonlighter
Kynseed
Forager
Graveyard Keeper
My Time at Sandrock

Cozy Grove

I tried browsing the relaxing tag,
number one best seller in that category... Elden Ring 🤔

https://store.steampowered.com/app/1455840/Dorfromantik/ is a great relaxing game on Deck.

The Long Dark <3
Tales from the Borderlands <3

Definitely not Cuphead 😅

But i'd recommend Cookie Clicker

I legit thought I might have something to recomend but after taking a look at the list of games I played I'm starting to think that I may be getting "relaxing" and "slow paced" mixed in my mind, after thinking about it for a bit quite a few of the chill games I remember playing either require constant attention or are actually kinda dark/heavy on their tone.
I did find one that's legitimately relaxing tho, and I played it at least twice so far (only once on steam):
Zenge

short hike gameplay time
journeygameplay time
the last campfiregameplay time

I highly recommend this game https://store.steampowered.com/app/1472660/No_Place_Like_Home/ it is extremely relaxing, kind of similar to stardew but it has less story but you don't have to worry about day/night cycle affecting the game.

As it wasn't mentioned already I'll throw my hat in for Down in Bermuda right now available in Steam summer sale at historical low.

I find the Trine series to be a relaxing puzzle platformer.
Though there's is some fairly straightforward and simple combat, there's virtually no penalty for death. The large focus of the game is using a variety of abilities to solve puzzles.
And even though a lot of players play Trine as co-op, you'll still get the full experience going through it single player. It's really great.
