Sword - Part 2
There is 1 bolt in this section, near the end after riding the lava-boat down the waterfall
First Screen
The intended strat is to push the right button of the boat while the lava geyser is down, then ride it to the top.
Ball jumping is clearly faster, however it is trickier than it looks. There is a rhythm to reach the top without bonking on the ceiling, and not going too far right into the geyser.
Second Screen
You have a short period of time to slide across the two sinking pillars without your slide stopping halfway across.
Third Screen
This ball jump is tricky
