Hi, I’ve just put a work in progress game online for you to see:
http://www.gempukku.com/gempballs/gempBalls.jnlp
JDK1.6 is required and at least 1.6.0_13 is recommended (because of graphical pipeline enhanced from that version).
I’m mostly interested in comments about the animation and what kind of FPS are you getting (shown in lower-left of the screen), what machine are you running it on and JDK.
If anyone is interested in continuing work on the game, feel free to post here. The game is developed on SourceForge, as part of the animation engine. If you wish, I can give you access to the project, so you can focus on the game, while I can continue with the core engine development.
