Another somewhat modest looking screenshot:

I've added the hogline and the backline using the player 0 and 3 missiles. I can't use players 1 and 2 because they will turn red to match the inner ring.

Most of my work this week was behind-the-scenes type stuff. I've redone the display list and memory layout to allow the bottom ice sheet to pan to the right with the shot. The top sheet will always show the house so you can see what you're shooting at, while the bottom is where you actually play. At the end of each shot, the bottom section will have scrolled all the way to the right and both sheets will show the same thing.

I need to figure out exactly what the rocks will look like and start figuring out how I'm going to efficiently move them through memory.
