When the game combines puzzle and horror elements, there is a safe balance that needs to be sorted out first. I love the idea of 1 minute stress inducing gameplay, which this particular piece has. The atmosphere is great, sound design and neat, visuals are raw and creepy. Yet, the main aspect of it - gameplay - needs a fix up.
To start with, I tried to interact with the keypad, as told via a short text/tutorial by pressing E and for the first 2 tries it did not work. The movement is a bit dizzy, in terms of a character leaning towards one direction. I tried to fix that by tilting the screen a bit, which was fun to do actually, but still, there is tilting, which personally was not my cup of tea. But, the main issue is definitely the first puzzle, which I did not complete and after couple of tries gave up on the game. Now, I don't say I am an expert in puzzle solving, although I've had a chance to play some unique games with puzzle elements and the main key about it is to challenge the player without them being frustrate. The complexity sometimes breaks the immersion and you don't want that with the game, considering that this also is a horror game.
In short, a simple update could fix some of those things and I definitely am interested in what the game can offer to the players. Best of luck with the project. Cheers!
Edit: The foggy effect is great btw.
