So I played KTAA. I'm not very good at it. I died on level 2. I was looking through the manual. I saw a rather impressive-looking screenshot of a mountain on screen 6. I assume that's + graphics and not available on an Odyssey², right?

I worked some more on my own game, ZipZap. I added a fifth level in because people were doing much better than I was. In level 5, there's a shark that continuously moves trying to attack the player. I am especially impressed with the way I got the shark's fin facing the correct way. In earlier versions it "wobbled" (went back and forth between the two shapes) when you and it are in the same x position, but I am also impressed because I actually managed to fix it.

I know of at least one other game that uses the gray triangles as a shark fin ("Sea Rescue"), but hey, what else can a triangle character be? Since I am terrible at it (terrible...at my own game), I made a version that starts on level 5 so I could test it, same as all the previous versions. I tested levels 2, 3 and 4 by making the game start there.

I used a little over 1,800 bytes in bank 2, so I have about 200 bytes left in case I want to change something. I am glad it's 2,048 bytes instead of 2,000. If it was 2,000 Pipe Down wouldn't be possible (I used 2,044 bytes in bank 2 of it. So, almost full!)
