When you launch a massive gaming application like Kongregate did yesterday, you should probably read the Android Developers Distribution agreement which clearly states that you can’t provide an app that allows people to download other apps. And since they didn’t, their app and its 300+ Flash-based games is gone and will probably not be returning any time soon. Google definitely frowns upon anyone looking to distribute apps through other apps that they might have downloaded from their market. They have zero control over anything when this happens, and while they are pretty lax for the most part, this is a serious enough situation to warrant such a removal.
You can still download the app here.
