[Spoiler] Final Boss difficulty after Patch #3

[SpaceJump]

Cannot for the life of me beat the final boss after hushing all envoys. I have all damage upgrades.

I can beat the first form, but the second form throws so much at you at fast speed. It seems the second form has so much HP. I managed to stay alive and deal much damage, but still he still doesn't go down.

I watched a YT video of the fight from before the Patch #3 and ♥♥♥♥♥♥♥♥♥, the difference is night and day. After Patch #3 all attacks are much faster, much more in quantity and the boss goes down in half the time I stay alive now. Much exaggerated after the Patch imo.

I'm about to give up at this point. Which is sad because I enjoyed the game till now.

So did anyone beat the final boss after Patch #3?
Any tips for what equipment to use? I use the soul that makes me invulnerable when dashing. What else?

EDIT:
Managed to reach the part of the 2nd form, where the crystal balls appear. And ♥♥♥♥♥♥♥♥♥, everything becomes hazardous. The complete floor, the small platforms burn, the fire balls fly at you, the lasers... And the fight just goes on and on. Yeah I'm out. Not coping with this. Not worth the frustration.

I bought the game pre-Patch #3. The info that I got is that the game was not hard back then. But now that I found the time to play the game I find a complete different one when I compare it to YT videos.

I bought this game after the patch 3 and just clear the game. I read some reviews mentioned the game is easy, but after the play through I started to wonder if my game skill is getting worse; but now I know the reason why...
When I first met the final boss, I died many times in the second stage. I really thought it's impossible to beat the game. Then I accidently found that there are two types of lasers. The thicker one with flame effect, this is the trouble one, which will cause the platform to burn. However, the thin one doesn't!! The trick is easy, you just need to follow the thin one to circle around, and you will not burn when you step on the platform. After that you will think this boss is even easier than the previous one. That is my strategy for your reference.

Ok, I just beat it. Paying attention to the thickness of the lasers would have made it easier I guess. There's still so much going on in that phase.
I still believe the HP has to be toned down. Also for the other bosses. Something between pre-Patch #3 and after I guess :D

I think many will buy this game seeing reviews on e.g. Youtube, which state how easy the game is. These reviews are still up and won't go anywhere. That's why imo this has to be addressed. Maybe difficulty or accessability settings would make all kinds of players satisfied :)

Anyway, thanks for your answer :)
