Legacy's End Space Battle: how to you beet this? - eviltoast

At this point I’m ok with finding a stupid cheese for this. I’m so over this.

I sided with UC, got past the 3 batteries, and am now duking it out over the Key. I’ve taken out the turrets, but the ship keep shredding me.

Had I known this battle would be such a massive jump in difficulty, I would’ve grinded longer to go into the battle with a better ship and better flight skills.

Any tips on how to get past this? I’m not having fun anymore 😔.
