Even if you correctly complete the level, you'll still 'fail' if you don't do it in the order intended. I got stuck on level 15 for a while because of this. (Spoiler), try changing the Orange to Pink, then Pink to Blue, Blue to Green, Green to Yellow. The entire screen will be yellow, but you'll still fail.

I feel like someone punched me in the brain, pulled out my eyes, and pissed in my eye sockets. And not in the good way. I feel stupider having seen this. This is why bad things happen to good people.
