Alrighty. Now, I've Finally given this game a go(played for a couple hours). And i've got a couple of suggestions that I think can Greatly improve the game, and make it feel less awkward and more competent to play. I'm not sure how difficult some of them may be to implement, and some will require extra animations.
first, and most important. PC controls please.. Console Controls frankly suck. they suck bad. this is why console games use lock-on. because with console controls, you can't control where you're aiming or going.
to be specific. When your weapon is unsheathed at minimum, your camera must be tied to your characters back.
For exploration, I understand having it free, so you can check out your Char or whatever. But, you should always be aiming where you're looking in combat, otherwise it's really awkward and makes a title feel cheaper.
I imagine this should be easy to implement, especially if you were planning on lock-on later. I also imagine you'll have to create a couple new Movement animations and potentially idles, aswell as adding a transitioning or behaviour system for it.(i have no idea how this is done.) I have noticed your char kinda runs in circles when moving, which suggests to me you probably only have forward and maybe backward animations, so I understand it will take some work.
on that note. I have a Laptop with touchpad. So i'm not sure if you can zoom or not. but I couldn't. this ones more for me i'd say. but maybe add in Zoom to the +, and - keys.
Second. while blocking, you should be able to move around, atleast walking speed. it feel really awkward when you're rooted while performing any basic combat action, and makes combat feel clunky. you look at fighters for example. and they are almost always protected. whether stationary, re-positioning, chasing or getting distance from their opponents.
for Attacks. create ones for Stationary, and Forward movement. you could do side-to-side aswell, but that can also be a bit awkward(fallout 4, third-person). you could also do something similar to skyrim, with behaviours for free movement while striking(this is generally how all first-person PC games are), although that's not necessary, and will also make the combat feel a little less deliberate.
I recommend enemies having a couple different Combos of 2-5 strikes aswell, so you can kinda get a rhythm for them. they should be movement restricted while performing attacks though if you do go for full on pc. otherwise it will give the feeling of being unable to avoid attacks, which causes most people to complain the combat is just about button mashing.(I do agree with them that it's better for the rooted approach. But I'm fine either way).
last thing to do with combat actions. maybe add less of a recoil for all actions. it feels really awkward to go from striking to blocking(although, that might just be because of the lack of movement). and really really awkward trying to avoid blows and strike afterward. even after striking just as an enemy finishes their attack, I always seem to be hit straight afterward, as I can't move or block within that long recoil period. because of this, it sort of just ends up being a tennis match of waiting for the opponent to strike my block so I can strike back, which doesn't feel good.
and Also. I'm not sure if npcs have infinite reach, or if the game runs like a tab-target MMO. but NPC's seem to have Infinite reach, or seem to hit you regardless, if they are performing an attack animation. if it is a sort of tab-target system, where positioning isn't relevant. then I'd say get rid of Action combat Controls, and replace it with RTS style combat like your Isometric RPGs(Infinity engine games, Pathfinder, Pillars of eternity, Neverwinter Nights1-2, Dragon age: Origins.).
I would also say add a bench or Bed. or allow a rest ability, for waiting time and recharging health. or maybe add really slow HP Regen(like 0.05-0.1% a second). with these things added(I haven't got far in the game yet.), you could also do time based quests, or secrets. like certain things only popping up at Day/night or specifics like between 3-5 am(stuff like secret entrances Appearing/Unlocking, Certain npcs Appearing or offering quests/events, or Events playing out). these kinda Adventure game mechanics can really spice up an experience.
anyway, yeah. I'll play it some more later when I have time and maybe add some more suggestions.(just had something come up as I was writing this!!!)
