Well you basically already listed most of my favorites, except for the first episode of Bravest Warriors, a web show by Pendleton Ward. I love it because at the beginning of the episode they find themselves from the previous time loop dead on the floor, so they try prevent that from happening, >!but at the end of the episode they die anyway in the same way next to their other dead selves, time loops back and when the next version of them sees two other versions already dead they say nope and just leave without fixing the time loop. Because even when knowing they were gonna die they couldn't stop it, so obviously they couldn't do it, better to just give up and dip.!<
