"I seldom make MUGEN stages except when in bundle with some MUGEN characters (i.e. my Custom SD Luffy).
I found this "A Broken Classroom" interesting and very simple to make so I gave it a try.  Yet, my MUGEN stage making skill is suck-ier than my MUGEN character making skill, so please forgive me if I did terribly bad/wrong to this "A Broken Classroom" MUGEN stage.
 
- Animation:  a little bit :p
- Super jump:  yes
- BGM:  yes"
