Thanks everyone. My plan was just release this game and if I would receive some positive feedback i would keep on working on it. Guess i will continue on it <img src="smileys/smiley2.gif" border="0" align="middle" />
Rory , i noted down your idea, seems interesting. My idea was, in each every level has some different gameplay. For example, one level there are some cannons shooting at you while you try to do the objectives, other there are bosses, like a giant kraken and so on. Every level would have some achievements that would unlock new characters. But there is the Online Score, so to balance things every one should have the same ability, to be fair. That's why i didn't make every character with a different gameplay. But i will try to figure out some kind of upgrades that don't influence so much in the score result (Like, you customize the kind of Upgrades that spwan on the level, but you you have to buy then first)
Anyways, i got some good feedback on it. So i going back to work. Thanks.
