Alright, I played the hack.
: The palettes look good. Some were a little bright but not bad actually, the dark palettes were looking really good, good job on that.
: Nothing new, actually. The palettes actually made them look better.
: Good choice of music here, although some of the songs had very loud instruments, other then that, good choice.
: I liked the design, not linear, but some levels were short.
Now here are three bugs I noticed:
If you watch carefully, the palette around the apple is a little brighter then the bush. You might want to fix that.
The message box is surrounded by purple bars. You might want to change that to black.
Look at the ball on the chain, when it dissapears at the top you see glitched graphics. I don't know if this originally happens in SMW, but you might want to take a look at it.
: This hack is looking good and it has some great levels, keep up the good work! 9/10
