It's very refreshing to hear songs in a video game context, especially a jam, and ESPECIALLY more than one! I like your voice, and especially your lower register, and i think both your vocal and instrumental melodies are very good, and you seem to be a very good songwriter!
I think it's great how you took the silly platform of a cooking mama parody to tackle such an important issue, and i think it makes this project much greater than the sum of it's parts.
Great job!
