Earlier today, multiple interviews popped up online, with several websites and publications getting a chance to interview Kingdom Hearts series director, Tetsuya Nomura, along with Ichiro Hazama ('Melody of Memory' Producer) and Masanobu Suzui ('Melody of memory' Co-Director) regarding 'Kingdom Hearts: Melody of Memory'. A couple of these interviews can be read below, with most of the information discussed being similar across all interviews more or less. Several interesting things to note from the interviews is that 'Melody of Memory' is meant to be a spiritual successor to the Theatrhythm games (even involving the same development team) that has been discussed as early as five years ago, along with the fact that Disney actually pushed for development of the game, and how development was affected by the COVID-19 pandemic. Check out the interviews below:
