Metamorphosis Game Demo: A Study in Bitmap Collision Detection

It's been a while since I mentioned Bitmap Collision Detection and I thought a game demo was in order. As I mentioned earlier Bitmap Collision Detection works by taking a small sample area and seeing if it contains certain colors or if it's colors reach a set threshold. Below is a demo of a game I'm working on called Metamorphosis (inspired by Kafka's work of the same name). To play you simply make your way through the maze of dark objects without touching any of them.

So far this game runs very well. The only problem I've found with it is that if you move the mouse very quickly you are sometimes able to skip over dark sections. This is more due to sample rate rather than the type of the detection. Regardless of it's shortcomings, Bitmap Collision Detection has worked very well in my tests and it has the benefit of creating new levels with minimal code. In the Metamorphosis demo adding a new level is a simple matter of adding a reference to the movie clip containing the level art to an array which keeps track of the levels. The game plays through the level and once it is passed, moves on to the next level on the list without any additional collision detection code.
