Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it all the way through the top door. This uses exactly 14 tiles (with no open end) - more rises too fast to do the trick, less does not have the height needed to reach the door. Use angle to break spin, then a momentumConservingTurnaround as early as possible, right as you pass the above tile horizontally. Using the background for positioning may help. The second momentumConservingTurnaround is as late as possible, just before touching the above platform. A third momentumConservingTurnaround is used on the door as it is opening.
