I've made some great progress recently, and I reckon it's time for a new demo.

I've started working on the game configuration options, which at the moment means game length selection and multiplayer support. Here's the simple menu I put together for this:

Here you can see the plethora of multiplayer options in the game. The CPU options are currently X-ed out, since I haven't done up the CPU play yet.

In addition to the game length, the game also now detects the end of the game and also supports tie-breaker ends. When the game ends, right now it just hangs, but that's OK.

I've also added left-handed shooters! Eventually, your team will be fully configurable but for now I've just made the third shooter on each team left handed. Here's a lefty in action:

Also, sweeping is now fully functional. You sweep by wiggling the joystick up and down, using true Atari 5200 analog power.

There are still some collision bugs and possibly some scoring bugs. I also need to tweak some of the ice physics a little, but at this point the game is fully playable. Here's a download, the complete assembly source is included, as always.
