Going back and doing a little testing, using the powered up blast in the beginning of Stage 1 Section 2, presently I'm 31 frames faster. I'm gonna play around a little more at this one spot to see if I can shave a couple more frames off.
I also noticed in stage 2 a little hiccup in my controls just before the boss. Need to fix that too when I get back there.

WIP3
Stage 1 & 2 improved, Stage 3 cleared. I restarted at Stage 1 section 2.
Only thing is that I know I fired too many shots at the Stage 1 2nd boss (he seems to die in 6 normal or 3 power shots) but this doesn't seem to have cost time, and too many shots at the 1st phase of Stage 2 boss (before he gets the hatchet) and this may have cost a few frames. Ah, the downside of frame advance. ^^;;
The 2nd section of Stage 4 I know is gonna be a pain in the ass. Wish me luck.
