The game is great so far! did fain and lionel in nightmare.
Fain is super fun to play but there is an obnoxious bug where sometimes the roll is locked in place and doesn't make her move out of the way. A lot of time it's not too bad cause of I-frames but it killed me a few times. Especially relevant on the watcher and the golem because of their shockwaves and lasers.
I really love the boss design, they all feel very different, attack patterns are challenging but all feel fair, even those you go "bullshit" at first end up being pretty manageable once you know how to deal with them (except the random eye attack on the watcher, this one is still bullshit to me =p).
I played only two character so far but they also feel very different to play while still having enough similarity that what you learned from the previous character makes you better with the second.
Currently I'm redoing lionel story in novice to see what happens with other choices (especially wanting to abandon fain since I didn't do that the first time and seeing fain story it seems to be the canon choice), and I have two nitpicks. 1) Skipping a scene also skip choices apparently, I kinda wish it sent you to the next choice if there is one. 2) I think an icon in the scene selector for scenes where there are choices would be a nice QoL improvement if you want to try things out.
I also had a few issue where I softlocked the game when using the skip option which was obnoxious.
