Ok, but then you miss the barges on the right...i suppose that you can also get them, just a bit of precision.
Also, as i said in the journal: i think there's a routine for the very last part of fifth stage, which is basically:
safe spot-> enemies to spit bullets-> reflect -> back to safe spot. I think that this section should give you about 6k, or in general get you to about 25k.
Any ideas on the infamous "before the second mid-boss" of stage four? I now suppose that the purple needle bullets are the beginning of one reflection, and not the end...if so, it's purple needles + spamming eagles in one reflection. As for the rest...
Does this progression sounds more likely to you?
100+100+60+200+250+etc=710+M
And the following percentages and times:
100%/1;100%/1;100%(?)/28; 96%/50;94/95%/20: 0/40:
20 seconds in the fifth stage are to nail the very last attack on the second form, i think it's more rewarding than a few more seconds. Are you ready for an ST?
