I spent some time last night and today to work on this some more. Technically, I got a game now. But it wouldn't be a very interesting one. Unless you call Street Racer interesting. So I'm going to continue work on it. I put in title music, and added a rock or log to avoid. Put in lives. Added a sfx for hitting the rock or log.

I had a bump in the river, but I discovered that since I wanted the screen to be full, the river needed to have different edges. So I did away with checking with playfields and just checking with different variables instead, which, while making more work for the Atari 2600 to do, the tradeoff is it looks a lot better.

Even though the idea has already been done (U.S. Games did a game called "Raft Rider"), my goal is to make it be better. I think it looks better already. Raft Rider looks really weird and ugly.
