Fortunately, you're in luck, as the ceiling of the third "monster" at 97% has fake spikes. You need to stick onto the roof and avoid the small spikes. Then, you can go down to a "break" in the fourth monster's pillar and avoid the spikes that were supposed to block your way. That's how I got past 97%. (If you got the third secret coin, you need to fly up fast, though)

Also, this is a rare bug that may happen sometimes with certain auto levels. It seems that they're not the only ones making such a thing. It depends on the position of the cube - adjust the tapping to the song and you're fine.
