Hey I spent quite some time on this one, hadn't commented in case I would bet it in the meantine but let's face it I won't manage to at this point ;) .
The furthest pattern I managed to reach exactly once was the one after the one in the top right screenshot not counting the one in-between all I think, although the one in this screenshot I can't do better than pray and expect I won't lose too many lives, it's where I die most of the time.
The presentation is a bit rough with not everything perfectly fitting together (on the bright side these bananas are some of the best types of bullets ever, and the music is great too), but the boss fight is super solid, I love it.
Like yourself I'd also taken notes that the small pink diamond bullets are not easy to distinguish through the bananas.
That's a super cool entry, thanks for sharing.
