yeah; -heat has been a few things at various points, right now it's been hacked into being the short persistent immunity effect you after throwing someone (mainly to help throw be stronger against groups). the red afterimages effect was from heat used to be a universal install effect that had various effects that are removed right now.
-purification is a flavorful way to reset progress. i have been thinking about having checkpoints that gameovers send back to, which would clear up the purification and gameovering having the same effect
-hairpin data is the accessory tracking each sprite has a pixel marked to give x and y coordinates for the accessories to align to. this takes a long while to read the points off the sprites, so i have the game find and save all the points once on first start up, and then it re-calculates all the points if the game version number updates
