It would've been a 4 star if the boss battle wasnt so flawed. I have three of the strongest ship ( of the line ) with ALL upgrades, and all my skills are maxed ( accuarry, dmg, hull etc... ) and I still CAN't kill the boss even though I use the most expensive and best ammo ( dynamite ). He gets to 3-4k and destroys me, every single time. Impossible, you must get really lucky. No skill required, just luck. Tried it six times and now I give up on this game. Thank you author for making the boss meta.
