the moment i started playing this game, i noticed a lot differences. like for example:
-new items
-3 new themes with their own night time effects
-p-balloon is way more precise with movement, but collision is kinda wonky
-characters don't change in the NSMBU style(it's always mario)
-title screen and control options are always in spanish (thank god i understand spanish)
-some objects are un-usable
-there are new clear conditions, but the parts and status categories don't work properly
-no object menu for sound effects
-no select/copy-paste
-no way to make the water level go down
