Simplistic...but amusing nevertheless.
This game is like many other games that I've seen around the web...but it pulls off the gameplay so nicely, and at a size that is easily loaded in the blink of an eye.
I like the way that the launching of the ball is made by mouse-movement, instead of many other games that are keyboard-driven. It adds more interactivity, I think.
The only major problem I had was the lack of sound, even little bounce noises and such, but this matter is addressed clearly in the author's comments. I'll be looking forward to a sound-enriched version, but for now...back to wasting my day bouncing a ball!
