Congrats on the new personal bests! Great to see people still showing love to Rolling Gunner. As far as Auto Buster goes, there might be a strategic advantage to playing with it off, whereas Auto Buster on is easier but not as optimal for scoring? I don't know, but it shouldn't make a huge difference, the only reason I'd see you would turn it off is for scoring purposes. It's handy for survival play.
Also, cheers on the score updates. ;3
I'd love to watch that video Roo ^.^
Also... dammit! I thought you were closer with your 1.8B hahaha
Yeah, sorry. If I get a proper run going with milking (I can actually do the Stage 1 and Stage 3 bosses, I just need to survive decently afterwards!) I think 2.5 bil might be possible for me? It'll be tricky to get a True All at high rank though... I'll record and upload all the current best scores tonight. I may make that Original one unlisted though, it's pretty shameful how it ends and is easily one of my most embarrassing screwups in any recent playthrough. >_>;
ON A MORE SERIOUS NOTE:
I ran into an annoying oversight/bug this weekend while doing milking. It happened to me twice:
https://www.twitch.tv/bkroo/clip/Neighb ... E8q8myQ2p4 (I'm rewatching a replay and using the arrow keys to pause)
It looks like the point where you've collected enough medals during Power Up to get the red swirly animation that's supposed to show your Over Mode is ready happens right before the Over Mode bar actually turns red. Like, 1 or 2 tiny medal difference. You can see I get the red swirly orb animation suck into my ship, but the bar remains grey. I press the bomb button... and get a normal bomb. You gotta make absolutely sure the Over Mode bar is actually red to confirm it's ready to go, it seems. :/
This actually happened to me twice in one day. The first time I thought I accidentally pushed bomb twice in a row, but the second time I used a bomb when I thought my red bar was full I knew something was wrong, went and watched the replay... and made this discovery.

It only applies to this sort of score milking and it only rarely happens because the margin of how many medals you need for this to happen vs your red meter being ready is razor-thin, but it does mean you need to shoot the boss and grab another medal or two to actually ready your red meter.
