Hello,
While doing the grapple run for frozen shards, I noticed that there is a map design choice that I find very annoying for the minigame. There's a bump on the right of some pillars that makes your character get stuck a lot of times, making this minigame more frustrating to do that it's needed.
I, like a lot of players, can still beat it easily, but this small bump on the pillar (check screenshot) just makes this mini game annoying, as you repeat the minigame over and over again.
My recommendation would be removing the small bump on the right or fill the gap on the left, while leaving everything else untouched. This would not break the flow of the mini game, while also not making it that much easier.
