All things considered, I have some honest opinions that I would like to share, and please do not take this as an attack, because I speak this for you to improve for the future.
I will start with the pros:
The game looks great graphically speaking, and the story was a interesting one, though slightly confusing. I love seeing Caseoh every time with these games as well.
The cons:
There's only one, but its combined with major issues I tend to see with a lot of these kinds of games: The game feels like a drag to play, and it killed the immersion overall. (I could speak on the swaying camera, but a slight adjustment to the sensitivity helped out a bit.)
Firstly, there was no sense of direction in the beginning, I spent 10 minutes wandering around the office wondering what I am supposed to do. In a couple of instances I noticed the hitboxes were a bit difficult to interact with, leaving me wondering if I actually interacted with the element already or not.
The game is also too dialogue heavy, and very cookie cutter to other games I played of this nature, a couple of weak jump scares and endless talking. I got impatient a few times reading instead of playing. Horror is best expressed with less telling and more showing.
And lastly, the mundane tasks. Having to go through a lot of small, unimportant labors that have no real impact or relation to the story.
These elements created a sense that killed the creepiness and horror. The game is 30 minutes long, not because there's 30 minutes worth of gameplay, but because its forced to be 30 minutes with all the previous elements padding out the gametime to make the game to feel longer than it really is. Take out all the issues and the game would be maybe 10 minutes at most.
To conclude:
I hope these words help you, and I apologize if I come off too harsh. I see you have a lot of passion for making games in graphical elements, but your skills in story making need to be polished a bit more.
