> There weren’t that many projectiles in the first place so I felt that this would be useful later. However, considering that Chrome and Safari were struggling performance wise probably due to their garbage collector working differently, I resigned myself to implement it now.

I'm curious about actual metrics with regard to Chrome / Safari's garbage collector overhead. You still don't have a lot of "objects" in the video; when V8 is used server side it handles significantly more objects. (IE, assuming each sword is 1-5 objects.)

Are these engines canvas based, or are they generating HTML? Assuming they are generating HTML, are the elements removed from the screen when you are done with them?

In a lot of garbage collected environments, you still need to call some kind of close / remove method when you are done with some kinds of objects. (In C#, it's "Dispose.")
