Even Cascade and Tightrope City?
Wow... I know they're not non-100%able, but I have been unable to pull off the 100% Cascade solution, and I haven't even been able to find the 100% Tightrope City solution.
Oh and, the list of 20 levels that you can't 100%... at least one is wrong. "Compression Method 1" can be 100%ed through a glitch. And if I remember correctly, I've 100%ed From The Boundary Line before, though it might have been on the Sega version only(where one builder will clear the final bit, and the level has Release Rate 50).
