This is a completed first draft. For improvements I got better screen transition locations that saved 15 frames. I'm not happy with the Air Man fight since he got 6 attacks in compared to HappyLee's regular Luigi run where Air Man only attacked 3 times. Figuring out the boss fight strats will be a huge time save right. There's also the problem that I haven't quite figured out how to get fast acceleration on Luigi quite yet, so there's probably a decent number of frames to be saved there.
