Very simple and addictive game....good job! It's been interesting to watch your progression from one version to the next - vast improvements in each one. Keep up the good work (and I agree with chochanglang - iPhone app possibly??)!!
Truly one of the best games I've seen on Kongregate (or anywhere for that matter). I love the fact you can load other peoples maps and create your own. I would like to see more objects to interact with; maybe a fan or a variations of wheel sizes. Play around with different ground textures (increasing or decreasing friction) and have more dynamic obstacles. Other than that, great job!
