Got it straight... For me the key was to spot immediately that only one way to go can work, and I optimized it on the go for a direct winning (as I used undo, make it 2 or 3 tries).
So, one hint from my side: it's a puzzle that can be solved before to start by studying a bit. :)
(12 years ago) Hiihih, it took me 10 tries to notice the little trick. Sweet ! :)

EDIT 2023, 24th Jan. - this is such a good level, a lot of fun, discovering the shortest path. Has nice 2 offs, too! And is also good looking. :))
