I've had a few opportunities to play the Premium on site here in Perth and aside from the air balls it's definitely an enjoyable and captivating game with so much going on.
It's integration of theme with art, sound, and toys is spot on.
I was expecting with all the criticisms of it being a drain monster that I wouldn't enjoy it, which after playing it seemed harsh. Definitely if you don't pay attention or have a momentary lapse in concentration the ball will drain, but hey that's part of the challenge!
