Absolutely beautiful. Honestly I'd rate this one a must play for 2016 b/c it hits on a lot of the major sociopolitical themes that've come up this year (in the West, at least.)
The aesthetic brilliance didn't hurt, either.
You might want to warn of the flashing images in the scene on the third level - I wasn't expecting it, though flashing images don't bother me I know they're an actual medical issue for people with epilepsy. Wouldn't be too much of a spoiler to just make a note of it in the description I think.
Anyways this is one of my favorite free experiences I've had ever. Amazing job.
