Very close to perfection!
I'm a fan of the samsho style of fighting game, but this one has a few flaws that hold it back from being as good as it can be.
For one, I personally believe the reversal parry shouldn't be allowed during parry-stun. The parrying opponent not being rewarded seems a little weird to me, and like a bug rather than an intentional game mechanic.
The hitstun caused by Bladesmin's followup super can be reversal parried as well, causing strange interactions like one stab connecting and the second getting parried and so on.
I like the ideas of combos (such as Blade/Swordsmin's heavy BC light) being true if the opponent's blocking, but able to be reversal parried, it adds some depth to the system by making these short combos a thing, but not one you can consistently rely on, and having some interactivity by asking the player getting hit if they wanna reversal parry when they see the Bird Cancel and run the risk of the attacker waiting for the parry and punishing accordingly, or waste a bar themselves to bird cancel out of hitstun and be safe from most other options. It'd also be nice to have Bird Cancel only available while you're inactionable, such as in the windup, active, recovery, hitstun, blockstun or parrystun frames, so as to guide newer players into the feature's true function.
I've also noticed that the actual recovery frames of an attack end deceivingly _before_ the animation, which is rather misleading. This could be an intentional design choice, but it can be confusing to newer players wondering why the opponent could block despite the fact that they were still recovering.
A few features I'd like to see in the finished product would be a netplay tool, if dedicated servers aren't an option then a feature to host would be nice, as well as being able to change bindings, and having AZERTY keyboard support.
Furthermore, I don't know how close the game is to being released, but if you guys want to add some music (assuming you haven't already), you can reach out to me through icicleweavile@gmail.com -- I don't even wanna be paid, I just love this game and wanna contribute to it any way I can.
This is all I can offer as hopefully constructive criticism, hoping this game'll become the best version of itself. Toods!
