Really nice puzzler here! I don't have a bad thing to say about it. The design was really well done and I had a couple of "ahhhh! That's how you do it" moments, meaning you balanced that out very well. I finished it!
I didn't really think the music fit the theme very well, and I agree with SporkTank that the backgroud was a bit disorienting.
Still, a great submission and you should be very proud of it!
