ThisIt's pretty elliptical. If you want definitive answers and a straight forward conclusion, Returnal ain't it.
While I loved the game, and it's my personal GOTY alongside Dread, I think they took a bit too far leaving pretty much everything up for interpretation.
There is a bit of difference between been mysterious and even subjective. However, the points in the story just don't connect. The ending leaves you with more questions than answers. Even if you dive deep into log ship and glyphs (I did), you still cannot put together two sentences that are true to the "real story". Basically, you can make up anything for the story. The entire game could be just a dog dreaming or whatever.
Having said that, playing it for the first time and just experiencing the world, the environments and trying to figure thing out, still was very enjoyable. I still keep playing the game after more than 60h, doing random runs just because the game is insanely fun.
