Best I’ve got is sloths. And they’re only green because algae grows on them. And I know it sounds like cheating because they aren’t intrinsically green but before you completely discount it there are animals that wouldn’t be the color they are in a different environment. For instance, flamingos are only pink because of the seafood they eat. If fed a different diet they can be almost white.
As a legal matter, maybe not. As a practical matter I’m pretty sure it is evident.
Pog mo thoin! I only remember the rude stuff. Literally read a bumper sticker like one time and it never left after over 20 years.
The obsolete skills they are learning are “prompt engineer”.
Some of these might be a little more like 8 than 5 because they have storybook-scary but still mentioning for you to have a look and decide.
Lost Words - Beyond the Page
Unpacking
Epistory - Typing Chronicles
One Step from Eden
Wargroove
Tsioque
Technically not female lead but kinda close and definitely age-appropriate:
Chicory - From creators on Wandersong + Celeste. Not positive your character is canonically female but let’s just call it very plausible and you are filling in for the titular character who is called “she”.
Donut County (technically the male racoon is the main character but the only human and next-most important character is female)
Journey (likely canonically no specific gender but great game, no dialog and could easily interpret as female if you choose)
Not what you asked for but maybe consider:
Beglitched - No human characters other than the player, puzzle game with pink and purple hacker aesthetic.
Lovers in a Dangerous Spacetime - Androgynous animals and humans pilot a wacky ship in 4 player co-op lots of hearts.
In approximate order of how strongly I recommend but all are recommended
Sayonara Wild Hearts
Epistory
Tales of Berseria
Tangle Tower (Pair of male and female protagonists through the whole game and they are very balanced for screentime)
Wargroove
Recettear: An Item Shop’s Tale
Crypt of the Necrodancer
The Stillness of the Wind
Sable
Tsioque
The Flame in the Flood
The World Next Door
Never Alone
One Step from Eden
This is an interesting question but I don’t think it is restricted to green. Isn’t the same true of purple, blue and red? I’m not talking about just reddish like human hair or a red panda but truly bright red like a cardinal. I would imagine it has something to do with our evolutionary history. Complete speculation here but laced with a few facts I picked up. I hear the common ancestor of mammals emerged around the time the dinosaurs became extinct and was basically a tiny rodent like a shrew. I wonder if as a small animal that can’t fly or swim it had to hide a lot and basically just came in shades of brown. So maybe any genes for other colors were lost before that common mammalian ancestor emerged and although mammals have lots of patterns they don’t have many colors.
