I was really surprised when I first beat the world record with the time of 7.196, since I did get a ledge grab at the end instead of skipping over it like the previous world record did. Because of that I wasn't satisfied and I thought I could probably get a sub 7s run if I could skip the ledge grab. Now I didn't get a sub 7s time, but I did get close so I can't complain. This time I did skip the ledge grab, although I still hit the side and that probably lost a bit of time.
So the only real new strat I do is a different way of approaching the second wall. Ico did a Charged Dash into it, but I really didn't like that strat as it felt inconsistent and annoying. I instead just time a Dash Jump, that way I have height and speed for the upcoming wall. Now if it's faster or not I don't know, but seeing as I beat the record by a big amount it probably is.
I still feel like the ending leaves more to be desired, which means this level obviously capable of getting sub 7s and probably quite a bit further.
