Climbing to the summit alone probably doubled my death count, but putting my frustration aside it was a great capper for the main story. Having to use all I had learnt throughout my playthrough to reach the top.

Now I'm blocked until I find enough presumably blue hearts. Thankfully, the game segments the chapters so it's fairly easy to go through and find everything I missed. Found B-Side 1 challenging, although I actually died less than I did in chapter 3 with only 340 deaths. Decided I needed to break after that and hopped off. Will return to do more later.
