Damn, first off, my condolences to you...
I really liked the art-style and how the use of audio complimented the in-game happenings very well.
The gameplay is somewhat limited, but is carried by the story, which is clearly in focus. I fell there is so much more to this game than someone from the outside can see, like the store, the actual meaning of the ticket, the computer desks and so on.
The story is very compelling, and I am convinced he must have been a dear friend.
But really good work! And best of luck in the future!
