I actually like the concept of the game; Yellow = Coins, Red = Energy (?) and the rest I'm not too sure. It would be nice if there were instructions in the game?
Consider adding various images, or implementing a difficulty set (Easy/Medium/Hard) into the current puzzle, so that way it will convince players to play more, instead of just trying it out once then never again. And I think the music should be a bit more fantasy-ish than being all jazzy seeing how the theme is a fairy and such.
Adding more puzzles to the theme, or having a difficulty set (Easy/Medium/Hard) imported into the current image may make the game worth playing more with the various objectives then being just a simple one shot puzzle game. After finishing the puzzle on the first try, I doubt I'd play it again.
Quite the simple game as it is, having some more puzzles would be nice considering how easy and quick it was to finish the first one. Or, possibly adding different difficulties (Easy/Medium/Hard) just so that one can be drawn to play it again.
