Mario Kart Insanity Update!!!

Hey it's been a while but my multicup, Mario Kart Insanity, has been UPDATED!!!
New features:
-Moving Item Boxes
-Reworked some weird track mechanics (notably replacing huge jumps with cannons)
-Some other minor changes in track BGs, music, etc.
Please use this topic to (kindly) point out possible improvements for future updates, and I'll see what I can do!
Enjoy!

EDIT: Also check out the battle courses, haven't updated those in a while (link is in MKI multicup description)
