TY Miky for your feedback
we are still at Beta stage so we are remaking part of the code, finishing some design issues and all that sort of things
About dificulty, you are right we've just include some random levels and maybe some are too hard for the first time but those levels wont appear too son in the final version.
Keep an eye on the forum or add PangA+ to your facebook likes, we are still improving the game <img src="smileys/smiley17.gif" border="0" align="middle">
