What do the percentages mean in the overall leaderboards?
Solution 1:
32 cubes + 32 anticubes + 3 heart cube pieces @ 3.125% apiece => 209.4% max
- 32 cubes net 100% for the first ending
- 64 cubes net 200% for the second/final ending
Three heart cube pieces add +9.4% (optional, Easter eggs)
Anything above that 209.4% is from a broken anticube.

Solution 2:
There is a glitch that allows you to get one anti-cube repeatedly.
