So Just an fyi Early Access for all those this is buggy reviews if you want a better example of quality for free try the demo its been polished and employs tested and working features.
As for the full realease at 15 dollars? A ♥♥♥♥♥♥ steal still needs a lot of work for sure but 3 hotfixes in 4 hours of release is a good sign in my opinion the game runs smooth atleast for me (comps pretty good though) and havent personaly experienced alot of bugs.

Pros
1 Wonderfully creepy atmosphere
2 Weapons feel good and sound great
3 Demo for people who are curious but dont understand early access is not always great but leads to better games overall
(looking at you The Forest)
4 Voice acting may not be getting an oscar but has emotion and draws you in
5 Immersive game that could be fun and gets you into the moment like arizona sunshine

Cons
1 The devs are not AAA funded so could not get the testing in that would have helped
2 CURRENT lack of control preference settings
3 No time travel to finished product

Summery play the demo and if you like it buy it and enjoy and if you dont want to deal with early access just wait for 1.0

1 Demo has been polished using multiple builds builds are completely different for a demo and an alpha build for a full game in most cases the alpha for full game probably did not even use demo build.
2 Solving issues in the demo if you followed it from day one is obviously based on massive amounts of feedback by players as team is small and requires outside testing as well as the crazy amount of hardware configurations being used that I somehow doubt can be recreated using a small dev teams computers
3 Early access is the only honest example of devs selling a product with an open statement that bugs will be there while on an almost amazing level large AAA games are released as bug riddled messes so to qoute
"Early Access Game
Get instant access and start playing; get involved with this game as it develops.
Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development"
