An excellent example of how to make a game.
This is very different from most other games. The graphics, all the way through, were top-notch, detailed and colourful. Couldn't have got much better. The music suited the game type and the sounds used were also well suited to this game. The game itself was challenging, yet fun, an awesome combination. For an improvement you could have added a tip or two for each of the more challenging levels. Well done on this, it looks like you've put quite a bit of effort into it.
