early power bomb: sanctuary entrance
Follow the video to get this power bomb expansion without the spider ball.
The toughest part is the second to last set of screw attacks, done from the ledge behind the blue cylinder. Just make sure your first jump goes all the way forward; since you have to start behind the cylinder, you'll want to get on the edge and jump out at an angle. Enter screw attack mode at the peak of the second jump, and delay each screw attack to get the necessary distance to reach the other side.
- You must still collect the power bomb itself at some point to finish the game. Otherwise, the ing flying cache in Dark Oasis will never appear, preventing you from getting the Sky Temple key.
