I finally got tired and gave up. I also have some trouble with my frame rate, but that's been a problem on my browser lately, so I'll try it again on another computer of browser to see how it goes.

If it weren't for really choppy play for me later, I'd easily have gone much higher in score. Anyone else seeing choppy play when the screen gets full of typeroids and a lot of particles?

Good game concept, I think. I like it!
