random balls

Game bug: balls can be seen underneath the level! (Also flickering on & off madly.) And the iron block that jumps out is shivering constantly, weird!

But there is only one ball that goes to the top and you can catch it

I had a hard time winning until I rotated the view to directly overhead.

@Chris Hester - there's more info about the oscillating block phenomenon at this thread:

@fares I worked out how to win. Note: sometimes one of the blocks that fly out at the start stays inside the hole. Othertimes it shivers against the back wall. So it's interesting that the physics is slightly random.

As for the balls, I took a screenshot of them going underneath the play area. They flicker on and off (probably as nothing is meant to go there normally)! I see dozens of balls rising up and then falling down.
