Pacing - maybe, but the only issue really is the "you have to stop this statue now vs there is this huge world I want to explore first"
witcher 3 had the same problem. they give you this quest that screams "TIME IS OF THE ESSENCE" but then they fill the game full of distractions like "hey don't you wanna help the local police solve a murder mystery???"
Through almost the entirety of Witcher 3 you're constantly waylaid, you don't even know where you're supposed to be looking for the first half of the game so it makes sense to just do witcher stuff.
Pillows 2 plot never really deviates from "Follow that giant statue!!" except for a short detour on how to get to the whatever island.
If instead of a giant statue he was instead a reincarnation you had to track through the various islands, dead ends, people purposely misleading you for their own reasons, etc., it would have been a more interesting plot and gave you a bigger reason to do sidequests.
