Spoiler warning!
So now that I've managed to actually play Sunken, I thought I'd give my impressions. First the stuff I liked. The atmosphere is quite good, I like the idea of starting off mundane and then ramping up to reveal the horror. The ambient background sound that plays after a few days really got me on edge. The jump scare on the platform got me good, too. The story is also fairly straightforward, and while not super original, was at least clear enough to figure out things while still leaving a bit of mystery.
Now the stuff I liked...not so much. The game is way too dark. I'm playing in a dark room and could never get the screen brightness to a level where I could see very well. I think there was supposed to be a car at some point? And maybe a ship out in the water? But I could only see about 2 feet in front of me and it made it hard to play, plus gave me a headache.
The last day of garbage collecting took way too long to find everything. And then I went underwater. I was happy with the visibility, until I discovered I had to run through identical areas with my vision completely blocked by kelp. I had no idea where to go, but eventually discovered I needed to find stones. Then some kind of monster/fish/thing came out of nowhere and got basically got stuck in my character until I died. I tried it a second time but the fish came out again and stuck through the character until death yet again.
I want to see the ending(s), so I guess I'll just have to check out Youtube. So basically A+ for atmosphere, C- for gameplay to my sensibilities.
