This prototype isn't bad by any means but it has glaring flaws I want to point out during my playthrough
before I get into the negative stuff here some good things, and I do recommend testing the game out for anyone reading this
1) style is great and feels good
2) the movement feels good
3) parrying feels good but it does feel a bit forced as a main mechanic
Negative stuff now
1) it can be hard to tell when an enemy will attack (mainly in crowds) due to the size of their weapons, although it's not the worst if you're able to keep enemy numbers low
2) the difficulty can make features feel like they lack depth, stuff like the dash is pretty much just "get to safety button" having dash serve different play styles could be more interesting like being able to dash behind an enemy and quickly attack but enemies act to quick to do anything other than hold the S key and press mouse 1 and 2.
3) ninjas kinda suck. they are more complex then the bowmen but they show up before them, the shuriken they throw can be hidden behind enemies you're fighting, and the combo attack can be annoying to deal with when trying to take down other enemies when stunned, and biggest problem is the stab attack, it's really fast and the notification for it isn't very noticeable, the stab needs some change because it can feel really unfair at times.
Overall it's good just not the most enjoyable at times, I can see the potential.
