Slide Puzzle

For my third game I wanted to try some 3D and so here it is in isometric projection. As you can appreciate this is no normal slide puzzle as there are two empty spaces and there is no unique solution. The rules are simple:

• Try to make a path from the left circle to the right by moving the arrows on the table.
• A tile can only move if there is one and only one empty space beside it. 
• The arrow on the clicked tile indicates the direction in which the other empty space will move.

Good luck!
