Use a complex lure to get the right-most Multiviola (which is initially moving to the left) to the bottom right door. Break a specific set of the speed blocks and let the Multiviola bounce off of them before breaking the rest. There are multiple ways to get the Multiviola to the right door, all of which require breaking the speed blocks to the left of the crumble bridge and some to them to the right. Break the speed blocks in one of the following ways: 1. The first 2 columns. 2. The first 8 columns. 3. The entire first chunk (10 columns). 4. The first chunk and all but the last column of the second (leaving an isolated block). 5. The first two chunks and all but the last column of the third (leaving an isolated stack of two blocks). Then let the Multiviola bounce several times until it is in a consistent pattern before breaking the rest. Note that option number 3 puts the Multiviola into an odd pattern where it has two distinct alternating cycles; wait for it to hit the right of the right stalactite, then the wall, then break the remaining blocks.

Dev note: It appears that there is no way to get the multiviola to get to one of the upper doors on the shaft; There are two known cycles to get it to start going up, but both get stuck in the same location. The first three Multiviolas aren't able to make it to the right shaft, regardless of how the door and speed blocks are manipulated. The fourth was tested by removing a single column of speed blocks at a time and clearing the rest before and after it gets to its cycle. The bottom door is rarely hit, but opening it during the cycle was not always tested thoroughly. It doesn't appear to be possible to lure it higher, but other things to try include: breaking speed blocks less than a column at a time, breaking some of the blocks then some more (not all of the remaining), or precisely timing the breaking of the crumble blocks.
