Live a Live

Played 31 hours, handheld and docked.
Beat all super bosses.
Did a 100 kill run in "Twilight of Edo Japan"
Got all cosmic gear.
Obtained the true ending and the bad ending (Odio Victorious).
Performance is almost flawless. Frame drops are rare and barely noticeable. Frame drops happen when killing a lot of enemies at the same time, outside the castle in "Twilight of Edo Japan" or during some rare graphically intense screens.
According to the patch notes, there's a bug that prevents saving in Dominion of Hate (final chapter) when attempting to finish the chapter with all protagonists because the save file becomes too big. This bug couldn't be replicated.
The last chapter is 99% the same if you play with another protagonist, it's long and there are no rewards for finishing the game with all protagonists. This bug won't be an issue for the vast majority of players. You can also work around it by keeping multiple save files if you want to finish the game with all protagonists.
No other bugs, crashes or issues.
