There are some nice cuts but as David said there are unfortunately many different ways to get 233. This could be a really good/tricky PP1 if one of those paths ended up being 231.
Feels good to solve another level with yfkd record. Many of the old levels are also hidden gems as well waiting to be discovered. I was initially misled as well.
I guess it would be interesting if there is a system showing the levels which a user hold the record.
