To get a light effect you would need an additional plugin.
They never advertised it as more then 1 game icon available. Those there just examples. Or do you want to also have the phone they've shown to be included with the software just because it was used as an example image there? ^^

Text based chat + multiple people writing at the same time = Chaos but you can re-read stuff ^^
