Generic sliding block puzzle (setting sun)

Don't let appearances fool you! This is a very challenging puzzle despite how simple it may look.

I themed this on a sliding block puzzle I saw online called the setting sun puzzle. The aim is to move the large thin 4x4 piece to the grove on the opposite side by sliding the blocks around (see pics for starting configuration).

Although I themed this around the setting sun version, the basic components for many sliding block games are included in this so can be configured to suit needs.
