It works for me in firefox, but you're not missing much. A lot of the time there is an element of luck - I had balls crashing together before I could do anything about it, as they were still off screen. 2/5
It has potential, its not the worst of this type of game that I have played, but it's far from the best. I'll be interested to see what you do next time.
Once I got to level 4 I stopped getting lines of blocks, so all I do is make 3's with the 5 colours - which is ultra easy. Great idea, but needs a little work.
There are better games like this - queuing actions is a must, and in most of the games, their life/boredom/happiness/whatever only goes down when they are waiting, not when they are getting stuff done, but its a good start. A few minor amendments and it will be as good as the rest!
