I guess I should make a record of having played Immortality.
Well, I say "played" but it's definitely more "watched and scrubbed".
I didn't find all of the clips but I did roll credits and I think I have a decent understanding of what happened. I would like to find the rest of the clips but the randomness of it has completely sapped my will to do any more. Maybe in a few months.
It was definitely a great experience, though I don't know if I'd necessarily recommend it. The randomness of finding new clips and the squirreliness of finding the hidden clips is frustrating beyond what the artistry can deliver to counterbalance it.
If you do decide to dive in, pay attention to the content warnings. Even with them, I was surprised at how much sex and nudity was involved. Definitely a step past Her Story in that regard, to say the least.
