I recommend Cobalt Core. Super cute characters and story, and very satisfying even after completing the main quest. It and Balatro are currently my standing “twenty minutes on a lunch break” games.

Monster Hunter series.

If you like english humor, check out “Thank goodness your here”. Alternatively “Tiny terry’s turbo trip” or “Untitled goose game”.

• Lost in Play - adorable game about two siblings and their imagined adventure…or is it?
• Tinykin - platform puzzler collectathon with zero enemies. Just cozy vibes.
• Freshly Frosted - Want to feel personally encouraged by a soothing narrator while making donut machines?
• Tiny Glade - make cute castles. That’s it!
• KeyWe - kiwi mail delivery. Literally.
• The Were Cleaner - werewolf janitor.
• Little Inferno - silly game where you burn things to get more things to burn. Also, Sugar Plumps!
• A Hat in Time - puzzle platformer collectathon that’s cute and creative
• Dangeresque: The Roomisode Triungulate - silly point and click adventure. Looks like I’m gonna have to jump…!
• Hidden Through Time - Where’s Waldo but more animated.
• Thomas Was Alone - platformer where Thomas might not be as alone as he thinks (in a good way).

• Cult of the Lamb
• Vampire Survivors
• Halls of Torment

Because you mentioned Islanders, maybe Dorfromantik?

My list of endorphin-boosting games:

Dorfromantik
Unpacking
A Little To The Left
Tiny Glade - though this one barely qualifies as a game

If you want something a little more gamified: Balatro is amazing and addictive.

Journey to the Savage Planet is grossly underated: fun, simple game, just challenging enough and extremely well polished.

Spiritfarer, it’s the most chill game I’ve ever played.

Oh, yeah and Dredge, one of my favourite games.

spec ops the line (just kidding)

I’m imagining someone cozying up with a blanket, a lap kitty, some tea, and the horrors of mankind.

The Last Campfire is like being read a bedtime story - its delightful

I should preface this by saying I don’t actually have a steam deck yet, so I haven’t tested these on there. So I’m only commenting on the games themselves. These are listed as deck “verified” in the steam store, though.

One I haven’t seen mentioned yet is Yoku’s Island Express. Breezy summer vibes, not much difficulty. It’s kind of a pinball metroidvania.

Tinykin is another game with a very cozy/low stakes feel. It’s an exploration/collectathon platformer with cute environments made up of household objects.

Littlewood is a life sim sort of game, kind of like Stardew Valley, but it’s extremely chill. There’s no time limit or anything like that.

And others have mentioned these, but Toem, Alba, and Donut County are all very good and gentle games too.

Oh, and Tchia. That one has some dark moments at times, mostly in cutscenes, but when you’re actually playing it’s mostly gentle and island-y.

Maybe also Wuppo? It’s a strange one. The story and humor and animation are pretty great in that one, but there are some boss fights that can get a little frustrating. It’s mostly a fairly chill platformer, but then it’s got kind of bullet-hell-adjacent bosses. I still really like the game, but it’s not quite as purely relaxing as some of the others here.

Pikuniku is kind of in the same position as Wuppo, but I liked it a bit less. The humor feels a little more forced or stilted, and the frustrating bits are because the controls are kinda floaty. My niece really liked it when she was 8, though, so it had that going for it.

Hope this helps! I’ve been looking for this kind of game a lot the past few years

Sayonara Wild Hearts. I love that game and often load it up when I’m feeling out of sorts.

Various levels of puzzle/chill:

• A little to the left

• Viewfinder

• Unpacking

• Bonfire peaks

• Moncage

• Chronescher

• Humanity

• Superliminal

• Manifold garden

• Gridroad

• Dredge?

• Far (lone sails and the second one)?

• Vampire therapist (maybe)

I would recommend grabbing this bundle: https://www.fanatical.com/en/bundle/safe-in-our-world-charity-bundle-2025 It’s got a kinda weird mix of games, but a lot of the games are great and several are fantastic for what you’re asking. Of particular note:

Edit: unfortunately that bundle is out of stock, and I just realized it. Sorry. My recommendation for the following games is still valid though:

• Little Kitty Big City - play as a cat doing cat things and exploring a japanese city. Very chill, fun animal characters, real fun experience.
• Thank Goodness You’re Here - very well animated adventures in a british town. Less of a game and more of an experience, but very enjoyable.
