I think with some work, this could be really awesome. But it sounds like a barely worked on WIP to me. It's just too simple. It's like you punched the notes in but didn't really craft the sounds.
But that doesn't mean your melodies aren't awesome, and that's what counts 4/5ths.
so 4/5 :3
accurate, I really do not work much in music, more for lack of time but I agree with you that could have been better, so I'll provide some adjustments: D
