More Actors Low Speed

for coins collision here is a snapshot
http://dl.dropbox.com/u/24541856/Capture2.PNG , i only i write maybe 2 lines to the console not to much and i removed them i face the same problem .

 the problem is not in coins specially because i remove them and added more enemies the slow return back so the concept when there is more actors the scene because very slow

Can you publish the game to the Arcade as a work-in-progress, so we can see it?

do want the game with slow effect (with coins and enemies)  or should i remove the all coins

Slow is fine.

i do not want to upload the all scene  Arcade so i make a link to you to test it
