A simple game that tests hand/eye coordination
The rules of this game are pretty simple: using the left and right arrow keys, try to keep the ball from sailing outside of the circle. Each time you succeed, the game gets a little bit faster and it's a little bit harder to predict where the ball is going to go.
As one can imagine, this is not a game meant to absorb you for any length of time, and it gets old pretty fast. However, as with many other games here on Newgrounds, it is entertaining for the time spent on it.
Suggestions: blocky text in the middle showing the "level" you're at needs to be changed to a clearer one, as many have said before me.
Other than that, good job.
