-You can move the 2 frame animated block around the screen with the arrow keys.
-When you press spacebar, the block's animation stops and the arrow keys can no longer move the block around.
-Once paused, the arrow keys will only control the pause menu.
-Press spacebar again to exit back to gameplay.
-There is XBOX 360 control support in there as well.
Note: There is a tiny bug where if you stop on item 2 and exit, then try to pause again, you'll have to tap the pause key (spacebar) twice. This doesn't happen with the 360 controller. It's a minor thing that you'll probably figure out why it's doing that by examining the event codes. I'll look deeper into it when I get a chance.
Note 2: The event code is a beast and there may be simpler ways to do this :-) Just giving you a fair warning.
