Hi! I tested your game and I thought I could give you some insights. I'm myself currently trying to make a game with first person melee fighting so testing your game was quite useful to me.
What felt great:
- the graphics and animations: the red slashes, orb picking animations, etc
- the impact is ok
- movements are great, the dash reminds me of Tracer's and feels great to use
- the parry move giving back posture and health is a good idea and works well in 1v1
What felt off:
- the parry move is only efficient in 1v1 or 1v2; as soon as 3 ennemies attack you it's impossible to defend yourself unless you dash in and out for every attack you want to land, which makes the game very slow
- landing more than one hit on an enemy might feel better it was staggering him instead of him just attacking like nothing happened
- not being able to block the shurikens since it's hard to see where the ninjas are throwing them
- animation driven combat with only hands being visible makes the telegraphs not very clear; when fighting more than one enemy it's hard so see when they're attacking
I think the main thing is that since enemies are attacking randomly, you can't parry them all and the block is so weak that you get pushed out of posture everytime you try to parry something.
I hope any of this will be useful to you and thank you for doing some devlog on this, it's cool having some insights on what may works and what feels weird.
