This is a tool-assisted speedrun. For more information, see​. TAS originally published on 2015-03-08. 

Take Square's RPG history & Nintendo's Super Mario series and mix them in a bowl. Add a pinch of comedy and a quart of luck manipulation. Stir thoroughly. 

This game doesn't count completion percent, but it still has stuff to accomplish to meet what's expected of a full completion run. The author, illayaya, defined it as follows: 
*  All depletable chests 
*  All menus unlocked 
*  All unique items/equips 
*  Kill Culex and Jinx 
*  Star firework in credits
