Interesting concept. Could have been better with more elements. Like exploding eggs which player must make sure to avoid or so. The game, as it is, is pretty linear types. All one has to do is look for a square bigger than 2x2 having same colored eggs on corners. The introduction of yellow eggs was also very late. I only played some 2-3 levels after the introduction of yellow eggs. If you have more elements in game you might wanna push them up the ladder.
