I never made it past 2 points, i had higher towers but they collapsed too easy

and I found a bug: the game often crashes after i entered my name, when trying to display the highscores. i think it only happens the second time i enter my name, it works right the first time i do it. when I'm starting the game again, the highscore where it crashes still got entered. I'm using windows xp on a very slow EEE pc, but the game runs perfectly.
