The Witness just starts right back off at the beginning unless you figure out the secret ending.
Returnal does this with several of its “endings”, but I haven’t been spoiled on all endings so I can’t say if it strictly fits.
One of Bastion’s two endings is a global reset.
I Was a Teenage Exocolonist plays with this in some interesting ways.
Dark Souls and Dark Souls 2 both have maintain the status quo endings.
I don’t like the taste of pure water. Filtered, bottled, doesn’t matter. It tastes bitter and metallic and it always takes effort to choke down.
I keep a bottle of unsweetened juice and use a splash of that to add the bare minimum of flavor I need to be able to enjoy drinking it at home, and when I’m out and about I just drink it and suffer.
Psychonauts (the original, not the sequel, though the sequel is also good) is a Summer Camp themed 3D platformer. It doesn’t quite meet your “low stakes/chill gameplay” criteria as it does have combat and mildly challenging boss fights and platforming, but it nails the rest. It’s easier than Tunic. Maybe worth checking out.
Brothers: A Tale of Two Sons strictly meets all the criteria listed, but it’s ultimately a tragic story. If “some kind of impact” includes leaving you in tears, check it out.
Okami is a Zelda style adventure set in feudal Japan with immaculate vibes. You play as the sun goddess Amaterasu in the form of a wolf bringing light and life to a land ravaged by demons. The world is cold and dark at first, but you bring spring and summer on your heels.
Finally, two favorites from my childhood are the Spyro series and the Ty the Tasmanian Tiger series. These are 3D Platformer collectathons and neither of these series are even close to any of the examples you provided, but they are bright and colorful and in my heart they have feelings of Summer Vacation and staying home all day to play video games.
Farming? Really? Man of your talents?
Air blowing over my skin is the worst.
Bright lights are bad, but they’re nothing compared to having a fan actively moving air across me. I can feel every bit of turbulence and it’s so distracting that it makes me want to stab something or tear my own skin off.
Now that it’s Summer everyone and their mother at work wants to have a personal fan on their desk or use a shop fan on the floor to keep cool and when I have to work with them it’s torture.
I’d rather be hot and just drink more water.
