Cave Story again

It is funny how I am faster at getting to Ballos with three health than I was with 55. I guess I did take a lot of time picking up health, but still, I am usually there in 8-9 minutes. Also I maintain that the area with the falling rocks is the hardest, even harder than Ballos. This is because I die there 95 times out of 100, yet I improve greatly on Ballos each time.
