Play 2 Scoring Limited to 1

[JoeKarlsson]

Observations:

• Player1 tends to score between 1 and 3 points when they score.
• Player2 seems to always be limited to 1.
• Player2 cloned objects don't seem to be able to collide with the target zone. They appear to pass through it, without counting as a
• win.

The easiest way to reproduce this is to move your ball to the wave above the target and drop down.

The same behavior was experienced in Firefox and Chrome.
I was playing the game through your public URL

The area where I'd have expected the issue to arise would have been in the switch statement within endGameCollisionHandler. My JavaScript is not very good. In fact, I think I stopped learning new things in 2008.
