A neat and clever puzzle - really enjoyed this one Kaboom! My guess is you planned some pitfalls and I fell for every one of em - all the more satisfying when I finished.
Great stuff - and no pesky UFOs either - double Thumbs Up !!
I think I did the same thing as Kazza, I fell for just about every trap that
you planted, at least once! But this was truly a fun level to play, and a
good puzzle to solve.
