Such an amazing demo! As said before by many others, the art style is pleasing to the eyes and gives off a comfortable feeling to it all. It truly is a well-put-together demo, regardless of the lack of music.
Chester himself is an interesting character. I'd like to personally believe he is on the more intelligent spectrum of stalkers due to the glasses sterotype, but through the interactions between the main character and him the events showcase him as a bit less secretive and defensive stalker; he drops his notebook accidentally and risked his chances of being discovered.
He's a bit clumsy but he's a very attractive and charming character.
