Yes, unfortunately, it my first time making a 2D platformer and I need to significantly improve my character controllers.
Glad you liked the music and pacing! :)
SPOILERS AHEAD:
It was supposed to be a sort of a "ghost memory" of the first body whose sword our character picks up, but it was pretty hard to reference that. The dead body is supposed to be our companion on this quest, but our character kills them because our companion is dead-weight. The narrator itself is the demon, who we had set out to defeat.
