That only fixes one bust. I've found another. It's possible, if you get the right timing on the ff slide, to exit via 27,23. This is assuming you still have the blue key and flippers.

Yeah, I see that one too, I changed some of the water tiles to closed toggle doors, so you can't push the block until you toggle the switch, which should fix the bust.

Or, after the flippers, exchange the blue key for the red key at 5,12 and continue the intended route.

That isn't a bust, exchanging the blue key for the red key there is a trick. The "intended" way that you might be referring to is not intended as the actual solution.
