Yooo this chiptune melody is damn cool! I'd just say the dubstep samples under are a bit too violent to go with it, I would have added at least some strong bass to make them work with something. The speech is a bit loud but very well integrated in context. The sound design is a bit too harsh I'd say, plus it's a little bit too stereo. Sad the song is so short btw. I'm saying it again but I really like the work on the melodies, they are very cool.
I hope this short criticism helped! Keep it up,
