Possibly very rarely, at specific stages, when code is heavy (many blood objects). Some blood might have problem in horizontal momentum physics cause of wrong multiplication but i'm not sure if its noticeable. First time i notice it at the shadow, as i put it always visible when player is high.Apparently this can occur during gameplay in Killer Instinct, but I'm not sure if it ever has any effects that would be noticeable to the player.
Now i make multiplications after h-blank finishes, or two times and compare the results.
