Linkaball

A simple yet addictive game that is very easy to learn - Create links of colored circles to make chain reactions. You have many power ups at your disposal as well as the ability to directly manipulate the environment with the mouse. There are many different types of circle to play with - each having a different effect.
This is my third game, kindly sponsored by Crazy Monkey Games. Any feedback will be really appreciated. Enjoy!

UPDATE - Front page and my very first award, it's like I've died and gone to silicon heaven! Huge thanks to everyone for voting, leaving feedback and/or suggesting Linkaball for a collection (Is it a puzzle game? I can't decide - what do you think?).

UPDATE 2 - A few people have commented saying that all the levels were locked - this is obviously some issue arising with Flash Shared Objects. I'm working on it but have thusfar been unable to replicate the issue, so if anyone has any ideas please drop me a line.

UPDATE 3 - Apologies for making level 20 so stupidly hard in comparison to the other levels - try saving up your points in the earlier levels then using the 'remove black/grey' powerups straight away on level 20. You wont get the highest scores, but you will complete the game (and get to the bonus levels).
Also, a big thank you to everyone for your feedback - the only way I'll learn is if you tell me what I've done right/wrong. So whether you love it or hate it, please tell me why and I'll donate you some Karma :)
(Oh, and thank you again to Newgrounds for putting me on the front page)

UPDATE 4 - If anyone comes across the bug where all the levels are locked, could you possibly message me the your Flash version (It will really help with debugging!). If you do not know which version of Flash you have, you can go to the following Adobe site - http://kb.adobe.com/selfs ervice/viewContent.do?ext ernalId=tn_15507
(But without the space in the URL - selfs ervice = selfservice).
