This was a fun little puzzle game (though I still haven't figured out level 10...).
I found it a little confusing that I got auditory feedback when the lasers were hitting mirrors and/or the target mid-rotation (but not where they would end up). It took me a while to figure out the details of how I could move and when the "you're hitting the target" sound actually meant that I was winning, versus just happening to hit it mid-rotation.
The music and graphics complement each other nicely. The sound effects are maybe a little bit loud compared to the music (a volume slider might be a nice addition).
Good level design, too, and it was fun to discover how things work through trial-and-error. Nice work!
