Having JUST finished replaying it myself last week, I wholeheartedly enjoyed your review. Thank you!
I had the exact same thought regarding the ending: the girl that in this game is so often depicted as vulnerable and caring (she loves her friends) is at the same time a ruthless serial killer who doesn’t seem to hesitate for a second about setting dozens of stranded survivors on fire who “just” want to escape the island as desperately as she does. When the final outro cutscene was playing and she ends with "I’m not going home…" I couldn’t help but fear for the next group of people she’ll encounter. ;)
Non-sequitur: OMG did I hate the quick-time events, though! Felt like I needed to fail at least 3x for EACH quick-time event before I got it right. /o\
Definitely “Abzû” and “Hellblade: Senua’s Sacrifice”. One is a beautiful piece of art that touches me every time I replay it and the other finally gave me a wonderful example to show to friends & family of how noisy it is in my head sometimes.
