I don't like it. Besides the setting it just seems like I've played it before. Also the parry and execution after is almost the same as Dishonored. Got Souls fatigue hard.
The game feels pretty good overall. You've got Bioshock-style powers, time-slow abilities, and a parry system that's quite forgiving. 1v1 fights are great, but things get a bit chaotic when multiple enemies jump in. My biggest issue is judging distance in first-person - sometimes it's hard to tell if an attack will actually reach you.
I really hope they add proper button remapping on controller (dodge on RB just feels wrong), and definitely more weapon variety - swinging the same saber all the time might get old fast.
The setting is easily the strongest part - finally something fresh. Those muddy battlefields with fallen French soldiers and smoke drifting through the air look fantastic and give the game a great atmosphere.
Overall, really positive impressions - can't wait for the full release.
