Do what Somebody said. Use paster. When you kill something then past corpses into a paster and delete the "corpse owner" or move it outside the layout (to reuse it).
You can have full red screen from blood and corpses, it doesn't matter.
Like I said in another post
It's using two Pasters in the background. One for blood and one for bullet holes. There are no problems at all. Game runs fine on desktop (chrome, firefox, NW) and on Android Crosswalk (tested mainly on my Samsung Galaxy S3)"
