Well, I don't know what I expected, but not that. This game is purely amazing, and a very good demonstration of video game as an art form. The gameplay is here just as a justification to make the player take a step back and think.
Only minor point that could be easily fixed is that the music saturates, especially with when the trombones are playing. It's not too loud though so it might be a mixer mistake where the track is pushed to saturation somewhere then lowered to a normal level later.
Anyway, really good job on this one, i'll definitly remember the experience!
