First, let me tell you that you're making a wonderful game.
The art, the lore, the gameplay, everything is brilliant.
However, I think the final boss is not balanced AT ALL. Right now, for the 4th time in a row, the whole playthrought was a real walk in the park and yet I got totally DESTROYED by the second boss.
I already beat him in normal difficulty but to be honest I was quiet new to the game and do not remember what I did, I'm pretty sure I got lucky seeing how it is impossible for me to beat him right now (by the way that is a shame that now I am more experienced the rest of the game is easy while this specific fight became impossible)
That's not normal. If the game was well balanced I should have been stopped before to fight him or at least have some issues to go to him but right now I'm just flying during the whole game and then BAM I got owned.
Let me tell you that despite the fact I love your game, that is really infuriating and to be honest, I won't even bother to fight this piece of crap anymore.
Last playthrought was the worst, as it deliberately hurt himself to proc it's ability (which could be considered as a great idea of ability if you just have to be smart and make it proc when you want it to do, but is stupidly strong if you can't prevent it)
This kind of thing (being crushed by the boss while the rest of the playthrought is a walk in the park) happened to me maybe twice in hundreds of hours of FTL, 'cause the boss and the whole game are really well balanced which tends to prove your game isn't, as I only play maybe 50 hours or so and meet this situation 4 times already.
And even if someone come here to tell me "git gud I won 90% of my games" that's great for him, but it doesn't change the fact that this kind of thing should not happened to anyone.
I repeat, If I got not necessarily owned but at least challenged by one fight before being crushed by him it would be all right, I could say my deck is bad, my choices were wrong, but that's not the case, even the first boss is easy as hell.
I don't want to be mean, I really love your game and just want to enjoy it fully, right now, that is not the case at all.
Maybe it should have a limit, maybe you should change the way it proc to prevent the AI to make it proc at will, to be honest I don't know but you have to do something, really.
