In Pizza Tower and (potentially) Sugary Spire, file heads are used to track the levels of insanity in PizzaBoy and Coneboy respectively, as the player progresses through the games. Similarly, in "Pridgette and the Castle," different file heads are used for Nealy, AJAYMAY, Pridgette, Dark Pridgette, and sometimes this game's version of the pillar. (except it is only the pillar guy who goes insane). Look in the project for the other file heads.
Credit to all.
