This is a status effect that
is caused by Seija inverts your controls, similar to the Confusion debuff from Terraria. You can get the same effects if you use the Invert Mouse in the pause menu.
- Inversion LXIII flips your player model, too, so you can be like Dinnerbone or Grumm!
- You can negate the effects (except for the gimmick applied at Inversion LXIII) by hitting Invert Mouse in the pause menu if you get this effect.
