More critically, the update disabled a specific exploit in the base XCI that allowed players to skip the "Waterfall Caverns" via a frame-perfect glitch. By patching this, Dlala admitted they do care about sequence breaking. Despite the "no wrong way to play" marketing, the developers enforce a linear narrative structure. The update reasserts authorial control. You will watch the cutscene where Goofy loses his hat, and you will retrieve it in the prescribed order.
The result is a game that looks like a movie. The deep irony is that the pirated XCI scene actually preserved a superior version of the game for a brief window.
