@Telapoopy: If you kill the small moabs too fast some bloons fly out of the screen and cannot be killed. additionally, during the boss level, the rings of red shield bloons appear three times, once on the far right. do not kill the boss too fast and kill the second ring, which appears on the far right, with some bloons barely killable and hardly on the screen.
if you keep dying now, go back a few stages to collect some legendary items, they're acutally better than your previously best items, even if these suck now ...
@RedeemedWahrior: they do, but their slow fire rate isn't sufficient to disable the shields quickly enough. i would suggest you take zakanas, as they have the same ability using missiles and can also buff adjacent units' damage. still, two won't be enough to efficiently disable shields fast enough.
@okupee: this upgrade goes up to 4 additional projectiles, which makes quite the difference in damage output.
if you are stuck behind obstacles you die when the screen reaches you and pushes you into the terrain. the same thing happens when you get stuck in terrain (due to a bug) and move towards either end of the screen - as soon as you get in contact you die. the only possibility to prevent this is using overdrive
Really great game! The only thing I don't like is being hit by bullets hidden 'behind' gems... An option which hides (or maybe even disables) gems would be really nice!
