(11 years ago) Good level! I expected more tries, but got lucky and solved it in 14. :)
EDIT 2023, 23rd June: just bringing stars this time. Soooo nice! :)
Finally found it! I was all along 10-20 off before I noted a way to not block myself too much.
Not sure why I didn't leave a comment on this one in the past, but only left a comment on another.
Personal notes: As at 15-11-2022, 7 more levels left before completing all PP1 levels. :)
This path took me so long to re-find. It’s not many levels that shut me down for almost 2 days anymore. Wish the path had more optimizations along the way which is the only reason this isn’t a 5.
