The main issue I have is that once I get to that boss I usually have 13-14 lifes stacked up, but then when I die 2-3 times during the fight, they put me back at the beginning of the pyramid part. (edit: after readin the manual, I figured out that the hearts are what brings you back to life after you die instead of bringing you back to the begining of the section)
If i die once, it's back to the beginning again, with little to no power ups on the way. I'M getting good at making my way to the boss without dying, but without any power ups, I have to kill the boss without being touched.
Last phase, I just can't figure out his pattern quick enough and I have to redo it all over again. I'll give it another go right now, hopefully i can make it to the boss with shield+ weapon upgrades
thanks for the advices
