Like Torm, I have also reached floor 13 without any new upgrades after the helicopter.
I do enjoy the game, but it's almost impossible to advance without Caravanserai, Galileo, and whatever else may come higher up.
Almost impossible to get a distance of 15.000 on a slower computer due to the animations - especially the plane flying by. I'd release the spacebar in the right time (I think, anyway), but due to the animation, the game lags and it thinks I keep holding the spacebar, thus jumping further and past the railpiece.
I've been having a problem; when I'm at the main menu and I press te 'Kick It'-button, my current cannon comes up from the ground and blasts the critter away, as it should. But after that, there's just blue screen (probably the sky), and it stays that way. This makes me unable to play, which is unfortunate, because I really like this game!
Great game, only one suggestion: move the "clear bombs" button a little further away from the ignition button - It really sucks to have to replace your bombs in some of the earth levels.
Can anyone tell me how to get the hard badge? I mean, I've finally gotten a score above 30.000, but I don't get the badge - not even when refreshing the browser.
