An alternate solution is to turn everything blue.
What makes Fiz interesting is that you never know whether it's easier to get a red solution or a blue solution. For the harder levels, only 1 solution exists.
There are 50 levels and I'm stuck on level 45, which I'm convinced is impossible. I believe that I've tried every combination of moves. If you manage to solve 45 - send me the solution please.
