Pros and cons are down below) Check out my vid here (the game is the 2d there) and sub):
Advantages:
1. Well, the game is scary. It is doing it's job creating a creepy ambiance and tension.
2. I love the concept of the game being inside the game, though I would adore if this would be underlined more. Like if you'd get to do something after logging out of your computer at the end.
Disadvantages:
1. I think the enemy appearances lacked nice accompanying sounds. It would be cool to hear something off after "finishing" the game before seeing the enemy. Or some basic jumpscare sounds would do as well.
2. It's a pity that there will be no sequel :( I guess this game feels a bit unfinished, indeed. Like there should be more explanation what has actually happened and why.
Overall:
I enjoyed the game! I think enemy model could still be polished a bit more and the sounds added but the game is good. It's 4/5 for me due to the lack of "final touches". I am exited to see your next projects!
Hope my feedback was useful!
