there are many levels that are smilar to each other :p gundu said that jp has said to him that its not a reason to reject level if it is smilar to an other level, as long as its not full copy of course :p
You are right, Asforien, this level is not possible. If we start from the end (blue at the right place), blue and pink are at the same position on the same 4x4 pattern. Since they can only move identically, it is impossible to reach the other position.
