Easy, Mark?
Not for me!
I cannot figure out what to do with the two shadows that are in the corner.
If I kill the rest of the shadows before them, then I can't kill both of them, and because of coins pushing reflectors in them won't do any good.
If I try to use other shadows, then again I can't kill both of them, since one of the reflector ends up on an edge.
If I try to make them face each other, I have to shield coins with reflectors, and the reflector-shield cannot be removed.
Totally confoozled!
