The Wonderland Board

I'm almost done, just have six levels left in world 10! Anyhoo, I have no idea how to get the reflectors in place to destroy the boxes, can someone please help?

I'm not quite sure if it's the intended way, since I didn't use the three reflectors at the right side of the level, but I played it this way:

1. Push the top-left reflector D, 3R and 2U.

2. Top-right reflector U

3. Lower woodbox 2R, and other box 2U. Lower reflector L, D, and R.

4. Let the UFO shoot twice.

5. Push the left box 2U, and the next left box 2D and R to get the bonuscoins.

Here's screenshot:

Got it, now I'm down to just four levels left, since I also managed to complete Five Squared, Squared while I was at it. Wish me luck!
