So far, I've played through all of level's 1-3, then skipped to level 5 and played both sections. The worst errors seem to have been fixed.
* There was some kind of garbage at the end of level 5-2, but otherwise the level was fine (see image).
* The spears that were invisible on level 5-1 are still invisible (see image).
* However, when you knock the foot soldiers down and the lay flat, they sometimes slide half way across the screen and disappear. They should only slide about half that far or not at all. It doesn't look like they are being knocked away; it looks like they are on an invisible conveyor belt.
