 They felt that this allowed them to create interesting ideas at the beginning of the game and then fill them out and resolve them at the end.One of these ideas was that of the "verse"; Holowka realized partway through development that he had been using the same twelve-note sequence transposed into different keys throughout the music, and realized that the idea of a pervasive musical theme to the world fit with the story.The game also includes a level and animation editor; several mods have been made for the game.
