My experience with this game today:
**** POTENTIAL SPOILERS ****
**************** READ AT YOUR OWN RISK ****************
I was walking through a corridor and suddenly I black out then it's filled with water when I open my eyes again. I hear something around the corner making a splash noise in the water and then I see the water splashes coming towards me. There's something in the water. I run and jump on a crate and it comes towards me then the water stops moving. I jump on another crate and it splashes as I jump then stops again. It is following me.
I keep jumping on objects and running small distances to avoid it and then I get to part where there is a dead body and I throw the arm in the water. The water splashes go towards it and then suddenly it goes under and blood splashes out of the water. It was eating it.
So I use that as a distraction to run further, then I get to a door with a wheel that needs to be turned to open it... but it was in the water. I have to rush to turn it while the thing is eating the arm. The door opens really slowly and I hear the thing growling and some splashes coming towards me. It finally opens and I go through and jump onto a box, safe for now.
Then I get through into a new area and I think I've got away from it. I start walking and as soon as I get around the corner I hear it again and splashes coming from behind me. I don't dare look back and start running. There are no boxes or objects in sight to jump on and I'm franticly searching for something to get on, I'm in panic mode. I find a small box and try to jump on it but keep missing because I'm so scared and it's right behind me.
I managed to jump on it but since it's so small the thing smashes through it and hits me and makes me bleed. At this point I almost screamed in real life LOL. I run for my life again and jump over some small objects blocking the water which slowed it down a bit. But as I kept running I hear it smashing through and quickly getting closer and closer to me. My heart is pounding. I was like "omg omg omg". There was nothing big enough to jump on I had to keep on running and trying to slow it down.
Eventually I get to a big door that leads out of the water and I take a big sigh of relief.
