I created a system for applying a fade to black and fade from black transition system when going between screens. While the transition is in effect, buttons are also disabled from being interacted with, instead requiring the transition to be complete before moving onto yet another transition to the next screen. This fading makes movements between menu screens less jarring and smoother. The fading is also useful to mask some viewing angle inconsistencies when moving between screens in the character introduction sequence as described.
There is also a lower priority possibility of adapting the same code later on to allow an alternate transitioning type where instead of a full screen fade to black, items from the first screen will fade out then the new ones on the second screen will move into position, allowing for the same background to be used, and creating the illusion of being part of the same screen.
