BADGES!!! Personally I don't find the hard badge very difficult. Then again I've played this for a long time. Also, as for anyone who says that it is sometimes impossible, you're wrong. It's always possible. The three columns will never have pels falling at exactly the same time. :D
Yeah, what CrazyBassoonist said about passing through objects... Obviously most things on the screen are moving to the left way too fast for the turtle to hit with regards to the framerate. But then again checking against the previous coordinates could be a bad thing since those damn spikes on balloons keep killing my turtle before I can reach 3,000,000ft. All in all, the game is tedious and overrated to me, but still well made. 3/5
