I used to play this game a couple of years ago. You guys have overhauled it so much, that it’s barely recognizable as the same game! However, I do recognize a couple of problems that I had back then, as well as now. The first one is aiming and shooting. I am very careful to aim exactly where I want the shot to go, and for some reason, it goes wide, one way or another, and doesn’t go where I had aimed! This usually happen when you’re about to shoot the winning bubble. That really pisses me off because I’ve just basically lost one of my shots and it usually just gets in the way of the next shot. The next problem is that once you reach a certain level (less than 100) no matter how well you play, or how many times you redo the level, trying different strategies each time. It will not give you 3 stars. That didn’t happen quite so early in the earlier version. And that pisses me off, too!
If necessary, you could add a drop-down box to offer subtle hints on what’s necessary to get your 3rd star. C’mon guys, it shouldn’t be that difficult so early in the game. If I can’t get my 3rd Star on every level, I will probably uninstall your game, and look elsewhere for something to waste my time on.
