~15 tries. It's not super hard, but it's very easy to lose moves doing silly things and the concept is just cool as hell. This level holds up in terms of fun and uniqueness over the years imo.
22 tries. This is a truly awesome level that is so difficult to analyze and has so many 2-offs that it's amazing. Needs to be put up for recommendation ASAP!
2022 edit - re-solved, 9 tries - still a cool level that holds up very well.
This is actually a great level and unique in that you can solve it first try through pure analysis and thinking logically about what MUST be done to achieve 98.
Edited. Sorry to those who already solved it - I found a bad 50 path! If you found the right path earlier, this shouldn't be a problem, otherwise :-).
Thanks to Manticore for testing, and Niels for finding an early hole.
10 tries so far - 1 2 off found...time to find the others
edit: done at 18 tries. Was a simple 2 cut, probably the same one as others. Didn't find any of the false 2 off paths - just figured I had the right path already based on the comments since I already had a great trick found...:p
