Good day! I've a few thoughts about doing maintenance to that quest. Here they are.
1. While talking to Egg Foo Yung, the camera should focus on him while he says his line, "So, it is time, then, to take the fight to Doctor Noh, General Tso's diabolical henchman? Excellent!".
2. Once defeating Doctor Noh in the Tai Foon Vortex, the MooShu 5's dialogue lines should all be changed from dialogue boxes to dialogue pop-ups, E.G., Egg Shen, "Now with Doctor Noh captured, the true target is at hand: General Tso. You should seek guidance from Egg Foo Yung. Let's go!", 'cause in every Skyway & Vortex in the Spiral's worlds in P101, all dialogue lines should be dialogue pop-ups, rather than dialogue boxes. It's not like W101's ways, you know.
Those are my only thoughts about doing maintenance to that quest. Hope they get done soon. Thanks!
