Transforming Blockies

Those purple blockies! These evil cubes have invaded peaceful lands of tranquility, where cubes of different colors are living, but they are NOT purple. Purple cubes were put into exile during the last cube war and according to Cubes Agreement, they are not allowed to step into these places like they could before. This day, purple cubes are all over the place and your task is to send them back to exile. They cannot stay here any longer. Find the way to remove them from the game screen and advance to the next level. Click on various cubes and change their size and shapes. Have fun.
