I saw it in IronPineapple latest video, and it really deserves more attention.
I absolutely love how art style, narrative and gameplay all synergyze to achieve flippant and dashing feel.
Gameplay itself is especially amazing. It could be most closely compared to Sekiro, with parry regular attack / dodge red attack fencing, and even this part is very satisfying. But it also introduces usage of environment, which makes fights against multiple enemies massively more satisfying. Generally in such games fighting multiple opponents is nothing more then annoyance. This game acknowledges the problem of having running around until enemies get properly separated, and gives you tools to separate them in style.
Also I really appreciate in combat and postmortem dialog, sometimes featuring appropriate movie references.
If it sound like something up you alley, I recommend you to check demo on steam for yourself.
Sekiro is the closest reference I know, but it is still quite different. Sekiro most important part is bosses, and I doubt En Garde will provide same variety (And if it against all odds proves me wrong it probably gonna become my new fav game). On the other hand En Garde focuses more on combat with regular enemies, and IMO does it better then other games with similar gameplay.
