For a change of pace, I decided to work on "Can You Canoe?" for the Odyssey². It took a long time, way longer than I expected, because the alien kept not displaying correctly. Level 4 is on the moon. I decided to make it so that the enemies zigzag after level 3. So the swimming alien moves up and down accordingly.
There will be a total of 6 levels. I don't know what to have happen after level 6, though. Perhaps just go through all the levels again and again until you die. I don't know what levels 5 or 6 will be.
I have gone back to being awake all night and sleeping all day.
