The physics in the coolmathgames version of circloo are quite different to the physics on kongregate, and those physics are different from the app version. There are several instances of level layouts being different on coolmath compared to Armor games, Kongregate, and the app. One specific example is level 6 and hard level 6 where on coolmath the balls are larger on coolmath to reduce lag. But in doing this, it makes the part slightly faster to play.
