Fine, we've had a week, no-one's posted, so I'll do Level 6 too. But I do wish people would get back to this thread; it's fun, and I'd like to do my levels here at some stage...........

Good: You need to use your skills carefully (you have just the right number of the last four)
Bad: The upper-left part seems a bit wasted; although it's necessary in order to leave you with just enough skills for the rest, there's no puzzle there. The trap seems misplaced, since it's so easy to get round. And there's not really any trick to the solution; all the moves required are pretty obvious.
