The art and audio combine to make an incredible atmosphere. I really like the backgrounds and the way the mouse scrolls the perspective. There are some really nice small graphical touches, like the rain landing on the top of the car. The voice acting is over the top impressive, though the audio levels are a little off between some of the characters. It almost feels a little out of place for the narrator to speak, just my personal opinion.
As some others have stated, the writing does feel very heavy-handed at times, both a good and bad thing lol The writing bleeds over between characters a bit, for example the street dweller and Ethan's letter feel like they are written in the same tone as the narrator, an almost indistinct style compared to each other. Certain longer dialogs might feel a little less daunting if they were maybe broken up into smaller segments rather than delivered in paragraphs.
One small bug I noticed in the inside of the theater, the hotspot on the left legitimately says 'Hotspot2d' on mouse hover lol Some tooltips/descriptions in the inventory would be welcome. At times it almost seemed like the 'dual click' system was unnecessary, like you could have accomplished everything with just one mouse input.
Nice touch with the puzzle rambling at the car though, that was very funny ^_^ Some very funny moments throughout, I legitimately got scared and laughed when Alex yelled 'Ah shit' after discovering a hole in the pipes. All in all this has some incredible style and vibes, and very impressive amount of content for the duration of the jam. Best of luck continuing the project!
