I'm not good at Rubik's cubes! I seem to remember there being a previous theme where that came up a lot (maybe it was the roles reversed one?), and it's still true now.
Anyhow, it's a neat concept, but some of the thing don't look enough like their symbol on the left for me to be able to tell what they are, and it was not obvious the first time I played that I could right-click drag to rotate the whole cube. It also sometimes seems to twist in a different direction than I intended.
