File 3: combat clicked beautifully for me.
File 4: WTF, stop throwing so much shit at me so I can actually enjoy this.
I swapped to standard for file 4 and I don't know if that's what did me in or what, but I struggled HARD for the first time since starting the game, and I feel like it was the camera and enemy / environment design working against the established flow of the game.
Trying to take down two flying fuckers, each with their own little immunity chain chimera behind them that you have to take out before you can fight them, was not fun. I hate, hate, HATE that mechanic. Tearing your focus away from an intense fight to hit L and try to line up a damn cut so you can sever the immunity feels terrible and clunky and distracting.
It's especially annoying with two powerful, aggressive enemies bearing down on you, and even worse when you get cornered and the camera has nowhere to go and you can't see anything.
File 4 also introduced boss and enemy encounters with large, random areas of ground that render you slow and useless. There's nothing I hate more in a fast-paced action game than this "the floor is lava" bullshit. Just let me play.
I hope they ease up on that going forward. If not, I'm going to burn out on this game way faster than I want. I was having a brilliant time until that chapter.
