This Game has great potential, and definitely fun and scary to play when you have Thalassophobia.
It's definitely got its bugs and still needs work, but overall I can't wait to see where it goes. It is clearly a passion project with a lot of love being put into it, with the concept, atmosphere and models being amazing.

My main issue I was having was my character being thrown around while underwater, making it difficult to exit doors and move around the sea floor at times.
I also had been chased and killed while walking around in the facilities for having my flashlight on.

I hope this helps and I can't wait to see what the future holds!

Played on Linux using Proton Exp, Not sure how to explain it but the underwater player controls like your in a mini tornado and walking on Ice?, Not at all like really being underwater in a heavy diving suit, So that alone pretty much killed the game for me, Very boring world, inside and out, Just mostly Empty Space, with a couple of objects/models, No real feeling of being underwater, mostly due to the players movements/control and the lifeless world, no bubbles, no seaweed, no little fish. crabs, rocks, nothing but the killer fishes and some sphere lights and buildings.

Sound is sort of okay mostly, the underwater loop sound get's a bit annoying.

Gameplay at the moment is just try to get to one building then another and so on without getting seen by the Fishes which results in getting eaten, when in a building you can pull a lever and remember the number displayed or listen to the computer log file, Also seems to have a bit where you have a nightmare so to speak.

At present with the way it plays underwater and the empty world i can not recommend it, as it EA maybe it will get Better/Fixed.
