A story game is no small feast, so congrats for having tried that format :) especially in a short amount of time.
It's great that you took the time to give some visual effects, and, as other says, the music fits perfectly.
Also, as other have said, maybe a little bit more player interaction would have been great, but in 3h there's isn't much you can do. So congrats, I enjoyed my time in the game :)
