I found a way to make it way easier. (The 3 fish parts)

Every 'line' that comes out, there's only three that will attack you. (the blue ones) Focus on them, it doesn't matter if you can't kill the others. Try to shoot three shots, per line, each killing one of the blue ones. I found you usually don't have to wait almost two seconds for your shots to reach the enemies doing it this way rather than firing all 8 shots at once.

Thank god there's a video for this. This one is by far the hardest level to get 5 stars on, let alone complete in my opinion, simply because the beat is not super obvious and those stupid swarming bots between open sections 2 and 3. I 5 starred every level on master first try (except Ill Still because I found the ribbon section to be a tad disorienting), and I can't even complete this one lol. Hoping this can help!
