Block Color Changing Puzzle, Can it be done? Options

[FireballDragon]

Hello. I'm working on a puzzle-based exploration game in the vein of Professor Layton, and I need help.

I'm stuck on a puzzle idea where the gist of it is:

You have 4 blocks in a line colored red, blue, yellow, and green in that order.
When you press the Z key at a block, the color of a block changes to the next in the order,
while shifting the previous color to the blocks adjacent to it.
The object of the puzzle is to turn all the blocks red.

Can it be done, or will I have to find an alternate solution or idea?

Ok, I will make you an event tutorial and post it soon.
