Thanks for the review! I hope you enjoy the game.
I worked on it non-stop. It involved a lot of research, and I completely rebuilt it from the ground up, including the GDD.
I don't know what GDD is. But I do not believe you. No human being can make that step in a week. Either you used AI for it all, but I rather think you already had this upgrade ready and are trying to impress everyone with your amazing learning capabilities.
Either way, it seems made up, because it is.
