During the Spoiler:Spamton NEO fight in Chapter 2, the player can exploit a glitch that forces Spoiler:the yellow SOUL to fire multiple charged shots in quick succession with the Z and Enter keys, pressing one while holding down the other.

A subsequent patch chose not to remove the glitch, but rather introduce a penalizing Easter egg based on it, where Spoiler:firing six to ten charged shots with this exploit angers Spamton NEO and results in his attacks scaling up in damage with each successive use of the glitch.
