The main way to complete the level is matching them. But you can also make them grey or destroy them with a bomb. You can choose for your levels with which way you want to complete them. This time it's the way of making the coloured blocks grey.
I don't know why people think that levels that use a trick need to be similar. Yes, you need to move a coloured block through a grey colour changer to complete the level, but it doesn't mean, that the levels are similar. You could have the level like there are several coloured locked blocks, instead of the grey colour changer, but it wouldn't be that simple and good.
Admittedly, this is quite a nice concept, but there have been quite a few levels where you need to shoot the blocks through a grey colour changer to complete the level. I still give this a 5/5
All credits to Sherlock for his idea 'EXIT'. As I am no copywriter, all I tried was to make his idea (with just one dummy) possible, and therefore if Sherlock wishes this level not to be accepted, I wouldn't mind.
