Answer 1

There's a speck of dust on the side of the final ramp which is very easy to miss (but if you use your super you'll get it). Other than that, fun stuff.

Answer 2

You can also light attack it through the ramp.

Answer 3

You tried to fix the map, but didn't fix the single biggest problem with the old version: the fog trigger.  All the background tiles are 50% black... and all the foreground tiles are 50% black.  The background that you can't stand on looks identical to the foreground that you can stand on.  Yet you have been using fog triggers in other maps, and you clearly know how to change them.  Please next time make the stuff you can't stand on contrast with the stuff you CAN stand on.
