Control is with the keyboard. Press the [left] and [right] arrow keys to move the wheels in either direction. Press the [R] key to reset a level if you fail, or if you fall off the screen. Press the (II) button on-screen (using the mouse) to pause.
You have a limited time within which to complete each level. If you fail, within the time allotted, you lose one life. Lose all 5 lives and it's game over.
Analysis: If you're like me, you love physics-based puzzle games like this. We've seen more and more of them lately as Flash has matured, and I never tire of playing them. Tudway gets the physics right in his implementation of the open source APE (actionscript physics engine), but the interface suffers from some bugs and glitches. Not so much, though, to ruin the experience. However, all Flash game designers should keep in mind the casual audience these games are popular with. Casual gamers generally prefer to play without being pressured with a clock ticking. For gosh sakes, don't we get enough of that in real life? Please don't extend that pressure to our recreation time, too. At least provide a "no pressure" infinite lives option to maximize the potential audience for your game design efforts. Agree or disagree? Sound off in the comments. In the meantime,
