So I was sitting there thinking that I was all better and ready to get back to work. The truth is that I ended up getting sicker than before and am just starting to feel better now. I did manage to finish the practice screen, which is a major part of the game. This is the place that the player will go to to practice drawing and pronouncing the kana characters and the words that they learn. After each one, the game will ask whether the player thought they did well or if they thought they didn't do well. Things that need more practice will show up more often and things that the player knows won't keep showing up.
I have a fairly detailed list of everything that I think I need to do to finish the battle screen. At over one hundred different things on the list, I'm thinking it should be basically working by next week. Hopefully I don't get sick again!
