I was confused by all the different ways to enter either from top or from right side in the first section. As I have no good intuition, it was for me a succession of tests, first to find out how to come to target, then until I find one bringing me 4 off, and then again until I won. Sometimes in the middle of the work, I lost the fun. Was then just relieved to finish. Totally counter intuitive in my case. I remove one star because of the loss of fun... ;-)
(12 years ago) Good one. But no idea as to why it took me 37 tries * - * :)

EDIT 2022, 18th Nov. - still a very cute level. This time it took me 4 tries :))
