First, very small board and many elements satisified the rules.
 * Seems this level is hard, but many moves helps. Five colours make the level harder.
 * Conveyor Belts moves the keys, make the idea easier.

Elements and blockers count: 10 (Really good)

Colours considering

 * If, then Impossible due to forever cascades.
 * If, then Hard
 * If, then Insanely Hard
