Not very good
This is one of those games that has its good points, but is very rough, and to be blunt there is a lot of work that can be done on it. The points system was nice, and the graphics were okay, as was the animation.
I would have liked some background music added in, and perhaps the most important thing would have been for the height to note what your height was at that time, rather than the peak. At the same time, the controls were overly simple, as all you could do was use one button.
It's decent as a game to get the hang of making flash games, but it's nothing I would go out of my way to play again.
