I've been working on a small side project for a few days just to test some stuff/performance.
Left Arrow - move left
Right Arrow - move right
Hold Shift + Left/Right Arrow - for slower horizontal movement
Up Arrow - move faster
Down Arrow - move slower
Space - shoot lasers (no point for doing that yet, but you can if you want)

I get almost same result on IE9 and Chrome. Usually it stays between 56-60fps but sometimes it goes down to 30-34 for a second or two and goes back to 56-60. Not sure why it's happening. There's about 150 objects (mainly instances of same sprite) on the screen +/- 5 for obstacles and some more for lasers.
I would like to ask you if You could play it for a while and tell me your highest FPS count, so I could figure out that jumpy frame rate.
Thanks to all
