Too easy, I'd say
At first, I didn't know what in the world what I was playing. Though the title did caught my eye. So I just went on with it and it was quite easy. It's probably the easiest game, I ever played today.
Just get high on the first level
I thought it was funny how I did not pass the first level the first time playing, because I did not even know how to get a high score. It really caught up when I was able to get past the first level with flying colors. After that, I could really just click anywhere and get way beyond the needed score. Anyway, I thought this was not the most original game that I have played. It is a completely harmless game, meaning there was really nothing negative about it. There was an interesting sound when the bubbles disappeared.
It was good.
The only thing I suggest is maby some difficulty levels to choose from.
Otherwise it was fun.
Keep up the good work.
Not that great...and It's old. I have it on my phone, still fun to play though.
