Now that's been said, great game! It was original and very fun! It's a bit weird to say, but it is very "natural" / easy to understand. When you see the light reflecting, the mirrors and the door, you know what you have to do.
One thing, I would just tuned up the volume of the audio a bit. Maybe it's just my computer though.
Other than that, it was a nice take on both the theme and the gameplay!
