He's not wrong about the new Sunrise Gate Zone music being inferior. I do disagree with a lot of his other points tho, as this was DEF not a spite fangame. Also, some of the guys working on this version are from the OG Team.
Obviously things wont be one-to-one with the OG Overture 2014 version as of now. Things will get polished as time passes by. But labeling a game as a Spite Project is such a dumb take, whereas the New Overture 2023 is trying it's best to revive and complete a beloved fangame.
