Hi there!
I just want to say that game is awesome. Very scary and interesting, but there are some things that I want to be changed. First of all, I don’t like that “pixel-cube image filter”. These pixels are very big I think. It looks good and old fashioned, but cubes are big. I thought that I have played in 480p resolution. And I didn’t understand how gun works. Why I can’t shot Siren Head from long distance? It seems strange to me.
So I think that it would be useful for you to make your game better. You have done a great work.
