Why is this replacing "y" with "i"? I naturally read "iear" as "ear", not "year". And I read "awai" as something similar to "uh-why" (I'm having trouble translating the exact sound to text). Other than that, I see no issues with the changes through year 5. It's not that hard to read and I'm sure I would quickly get used to it with practice. Past year 5, I don't understand what is happening and I literally can't read it.
