I'll just make this quick note right now: add a BG. Also, more hitsounds in Hard (the only difficulty I've scanned over so far). I just wanted to make these points noted right away. Expect a more detailed mod post very soon.
Just looking over each one quickly, there's nothing major to note in design flaws, etc. Just make an Easy.
