I wish I had a better computer to run through the entire game at a decent speed. The art looks really awesome, and the loneliness is transmitted. I would suggest polishing the rain loop so that it sounds constant and doesn't break every time the file repeats.
Apart from that, the game looks really interesting. If you manage to prepare an optimized version (for slower computers) I will be ready to try it again.
From what I saw, this looks great. Congratulations!
