I did a sequence break with the blocks in i believe the east marsh area. I positioned the blocks in a way that allowed me to jump all the way up instead of climbing the vines, which I believe game me sprout before wall climbing.
I'll be honest though I accidentally cheesed the final room, the collider on the final heart thing was a tad too big, so I randomly attacked when i first entered the room and just beat it. So I didn't actually get to properly experience that final room
