Tip of my tongue thing, but somewhere in 2020, I ran into a Steam game where you played a girl on an island (at a camp?) who I think is looking for her missing friend. I downloaded the demo to try it out, and ran into my usual issue with puzzle games, that I have a low level of frustration and found myself looking up answers. If I recall correctly, the character has three "buttons", one to jump, one to pick up/throw things, and one to regenerate. When she regenerates, all of her severed limbs disappear as they go back to her. I remember one of the puzzles involved her picking up an object and throwing it to dislodge an object in the trees. A later puzzle had the same thing, but there were no convenient objects, so you had to bump her against an obstacle to get a severed limb to throw. In another puzzle, you had to injure her down to just being a torso to make her the right weight to get through a particular balancing log puzzle. You didn't have to have the limbs nearby to regenerate them.
At least in the level I was playing in the demo, it was night time, and might have been raining. I think there may have been bonus items you could pick up that looked like donuts. I'm sure they probably actually have some sort of effect in the game itself, or they might have just been bragging rights. I don't remember if there were actual enemies other than the environment in the game. It was possible to "die" by drowning, or by taking one more injury when you were a torso, although it just took you back to an earlier checkpoint.
