Second what wolscott said, it's a bit difficult to decipher without a few pointers. Wouldn't mind learning about Phonology though so if you add some instructions I'd come back and try it again
Thanks for playing! Yeah learning languages is difficult. Even more so when you make a game based on edge cases. There is no particular order, I recommend skipping to I-mutation in plural nouns. Which contains mostly of Germanic nouns. A few pointers: the first answer of the first level in the I-mutation section is 'man', note how in English the plural of man is 'men'. When you answer all the questions and press the back button the level button will turn green indicating completion. Yiddish is written right-to-left.
