Loved searching for the last steps (for 166), here. First run I was far away, then came to 178, then slowly lowered in steps of 4 and 2 (was at 174, 172, 170 and 168, for quite some time). I find this a very good level.

EDIT: After two months I finally came to 164th Philosopher's Stone. A splendid level and a great title, too. :)
