Level 472

I haven't spent hours on this one, After about 10 moves and 20 shots, I end up with one block in the upper right area and nothing else to move.
Please tell me what I am missing.

The block is not the thing you need. There's a reason that P14-15 is bricks - it's so you can get the O13 AT out. You can use it to help you get to the flag.

Let us know if you need another hint.

[BOBWM]

That hint did it! Thank you again

No worries Bob. Congrats.
