Probably a suboptimal first phase fight, because I think I want to kill that egg he drops to get more hits in. But the point of this file is that the second phase of the boss causes the game to freeze, and I'm not sure why. But anyway you guys get to see the progress of the improved world 4. Yay.
file completes first three levels and part way into level 1-4. Also improved the first 2 levels by a small bit. This is just to show that the terrain script doesn't work on stage 1-4
