Lovely!
I love all these bubble shooting games, this one is nice too. I won't say that it's simple to play it because of shooting with your mouse. Have you passed 19th level?? come on, it's just unreal to complete it. and it doesn't matter if you shoot with mouse or not, it seems that you should solve it like a puzzle at some levels. too difficult for me to play further, i dunno.. maybe i should try once again
