Good art, but too easy.
Running into baddies, falling to your "death," or being shocked by a laser/electrical beam only made you lose a few coins, which were more than made up for by collecting coins on the level. That and the lack of action and easily solved puzzle levels turned this game into an easy time waster rather than something you would actually enjoy playing and replaying. That being said, although the idea of a castle escape game is unoriginal to the umpteenth degree, the graphics were very colorful, the scenes varying and increasingly interesting, the controls simple and fluid, and the puzzles inventive. It is also obvious that you have put a lot of time and effort into this game.
Overall, this game was enjoyable to play, if not perhaps for the gameplay itself, than for the backgrounds that were relatively unique across the 31 levels. If you were ever to make a sequel, I would recommend not eliminating the puzzle/acrobatic element, but adding an action element, be it as simple (and unoriginal) as jumping on your enemies. But I'm sure an inventive person such as yourself can devise a more unique style of gameplay.
