Pop... pop... poppoppoppoppop...
Great game, with a nice idea behind it.
My biggest problem with it was the unpredictability of what exactly will happen. I mean, it's possible to predict (nothing random), but you need a computer for a brain to keep track of all possible chain reactions and their consequences. For a while I thought I'd never be able to corner the computer. Just when I had it down to 3-4 bubbles, it'd pull something ridiculous like a 130 pop combo and take back most of the board.
Technically nothing special (graphics were okay and the music can be turned off), but it does the job and it's all great, addictive fun.
