Games you can't lose

Kirby's Epic Yarn. there is the level with the lava, if you don't touch the controller you still finish the level.

If youre bored and like idle games then id recommend to you NGU IDLE , but beware, this is a very addictive game.

LucasArts adventure games.

I`ve been playing Evergarden while watching a movie and some episodes for a couple of hours now, it's a puzzle game that has a lot of depth to it, while still remaining fairly simple.
I like how you can just play it as long as you want, and if you are planning to put a couple of hours, it is worth it to do the daily puzzle, using up some of the pieces you win, in order to have more plant growth in the beginning for all the future games you'll play that day.
It makes it quite rewarding, but not necessary, and just adds to the fun :).

Little inferno
also real-time games usually don't have any penalty to them, games like Adventure Capitalist or Viridi

I made a great long list of recommendations for "warmhearted" games a long time ago, so I'm going to steal a bit from that and maybe add a few more that are just generally not difficult. You seem to have played a LOT of games, or heard of most of them, so I'm going to get weird with some of my suggestions.

EDIT: I just saw that you don't want text heavy games, which is most of these. Let me fix that.

Adventure Games

Wandersong (Adventure) Save the world through the power of music! Or don't, maybe, but the point is to try.

The Frog Detective games (Adventure) Quite silly and light, only an hour or so each I believe.

Tiny Echo (Point & Click) Any Might and Delight game walks the line between being relaxing and being too slow. I thought this one got the balance just right.

The Dream Machine A handcrafted adventure game series, currently on sale for very, very cheap. Some horror elements.

Dujanah (Experimental Adventure) Sooo, this one's weird. It's kind of an open world? You play a woman in the middle of an unnamed fantastical Middle Eastern country looking for her missing husband and daughter.

OneShot (Adventure) No dying, just quiet contemplation and difficult decisions. To quote the game page, "You are to guide a child through a mysterious world on a mission to restore its long-dead sun. The world knows you exist."

The Cat Lady (Horror/Point & Click) Believe it or not, despite the gory trappings of this game, you can't actually die in it. Your character is granted immortality from the start, in exchange for her mission.

Fran Bow (Horror/Point & Click) Similarly to Cat Lady, you can't die in this one.

The Darkside Detective (Point & Click) A gentle, cheerful supernatural tale about working in the underfunded police department of a spooky town.

Shrug Island (Adventure) Bite-sized but beautiful game about connecting with each other through music.

Burly Men at Sea (Casual Adventure) A short, colourful folk tale about three bearded men. You fill out a blank sea chart and see what fun little adventures you can get out of it. Sort of like Sunless Sea, I guess, if Sunless Sea were child-friendly and had a much brighter colour palette.

The Norwood Suite (Adventure) Loved this game, despite its bizarre ending. There are just enough puzzly bits to keep it from being a walking sim.

The Witch's Isle (Adventure) A relaxing mystery game with the unique mechanic of solving puzzles by switching briefly to other character's perspectives to see what they're doing.

Puzzle Games

Draknek's games Cute, simple, fun.

Vignettes A cross between a puzzle and a webtoy, but you do make progress! Shapeshift objects using perspective to unlock more items.

Gorogoa Completely unique, breathtakingly beautiful. If you haven't played it yet, now's the time.

Visual Novels

Danganronpa (Mystery) The first and second games are great. There are some timed gameplay segments, but they're nothing difficult. I've never heard of someone losing. (It would be at least as difficult as losing in Phoenix Wright.)

Camp W (Visual Novel) A friendship sim with the graphics of a Saturday morning cartoon.

Purrfect Date (Cat Dating Sim) You can die, but the game actually incorporates that into the story! This did some really clever things with VN mechanics I haven't seen anywhere else, and it's a solid mystery game to boot.

Other

Under Leaves (HOG) A simple and pretty hidden object game.

Marvin's Mittens (Casual Platformer) A game about being a kid and playing in the snow.

The Tiny Bang Story (HOG) I tend to prefer hidden object games that have progress, but don't have the light adventure game trappings.

From recent plays, I can recommend this charming little gems:

A Short Hike

Yoku's island Express
https://store.steampowered.com/app/334940/Yokus_Island_Express/

And maybe this one can apply too. It was one of the best gaming experiences I had in a long time:

What Remains of Edith Finch

In No Man's Sky's creative mode you can't die and have unlimited resources.

To the Moon

https://store.steampowered.com/app/206440/To_the_Moon/

Story-based game. May be classified as a visual novel. One of those games that I torrented, finished, bought on Steam, then finished again.

Great game :)

I looked through the list of games I beat myself during the last few years, and I think these more or less qualify (some FMV games and interactive movies, some puzzle games):

The Plan (10 minute game)
Silence
Late Shift
Press X to Not Die
Tender Loving Care
What Remains of Edith Finch
The Fidelio Incident
The Walking Dead: A New Frontier
Finding Paradise
Last Day of June
Life is Strange: Before the Storm
Morph Girl
Gorogoa
A Way Out
The Awesome Adventures of Captain Spirit
Blackwood Crossing
Journey
The Quiet Man (2x, without and with Audio)
11-11 Memories Retold
GRIS
Observation
The Walking Dead: The Final Season
The Great C
She Sees Red
The Invisible Hours
Beyond: Two Souls (PC, Remixed version)
Her Story
The Dark Pictures Anthology: Man of Medan
The Complex

Although I will say that while those games are without death and can be played in a casual way, most of these require your attention in one way or another. I personally would not play a story-focussed game while watching TV, as I would be bound to miss a lot of either the game or whatever I watch on TV then. ^^

I mean, in other categories, also just Walking Simulators usually you don't die.
