This combat demo is still barebones bat what's there is solid (and also looks very pretty). I like how smoothly the character moves and I'm very curious to see where you're gonna take the gameplay (but please add some kind of respawn).
There's not much else to say so I'll just list a few possible bugs: The character can dash through walls (which I presume is correct because, you know, ghosts) but if you stand behind one enemies that get too close to the other side can hit you and noclip through. Also I found out that if you hold both mouse buttons and let go RMB after the spear attack, you can sometimes instantly chain a strong rapier attack.
Keep it up, it looks very promising!
