Blast Wave

Game description
Strange things have been happening in happy space recently, odd holes have been opening everywhere and through them have come angry circle people. The happy square chaps that live in happy space have asked you (very kindly i might add) to dispel these circular misfits back to where they came from. This is my second flash game so i hope you all enjoy it :)
How to play
+ Hold down the left mouse button to charge a blast + Longer you hold, the bigger the blast
