4x4 Colour Dot Puzzle

Hey, this one is for all you puzzle fanatics out there!! So I've been conjuring up a few game designs recently and I came up with this 1 player game puzzle that I find quite interesting basically if a Rubik's cube and a 15 puzzle had a baby this would most probably be the result. The aim of the game is to rearrange the 16 coloured tiles in a way that all the 4 different colour tiles form four 2x2 squares within a 4x4 square.
