I liked it, it was a fun little game. Pretty easy most of the time, but for a casual gamer, it was a good learning curve. I liked the adding of classes and the system that went with it. I wish it had more levels, but like the fact that all the levels were divided. 4/5
Adventure mode was OK, but it was rather short. The final boss was hard, but like all the bosses, once you failed a few times and got a strategy, it was easy enough.
What I think is the best part about these levels (or at least the ones that I have played) some of them look so easy! You think "Ah! What? This is a piece of..." and then you die eight times before you realize you're doing it wrong!
The graphics are good, but I agree that there should be real words. Also there didn't seem to be any negative effect when the bubbles reached the top of the screen.
