Level 7 is unbeatable on my end. Reset all upgrades, didn't buy the freeze gun, and still have kids that never show up so the stage can never progress. I don't know what's happening other than maybe there are too many sprites onscreen so when the card board boxes fall over no kids come out. I have full upgrades and still have to click the left mouse button as fast as I can, and its still not really fast enough to keep all the kids from banging on the truck. I'd like to get this badge but I've already wasted enough of my life on this. 1 star.
How can anyone beat or play this? I'm constantly having frozen kids being scrolled off the screen and not tallied as defeated, so I have anywhere from 1 to 5 kids remaining and the ice cream truck rolls on forever in limbo until I physically have to quit the stage.
I love this game, but it does need a little polish. A way to decrease plant cost, traps, bustable blockades for the special paths, and a way to cultivate the plants i.e. an upgradable weapon system that allows at least 2 possible weapon choices dealing either floor or air damage.
