I love the general aesthetic. The environment looks even better than last demoday. I'm not a fan of the combat. Reminds me of World of Warcaft, but I don't feel it translates well to the isometric perspective. Maybe add a button to quickly switch target (or make something like baldur's gate, where the character goes where you click). I would prefer if you could see enemies behind walls also when you're not standing behind them. Also, what's the point of sneaking behind enemies when they can see and shoot through walls? It's better to just tank the melee ones first with the armour and the lifesteal blade.
I like how took the initiative to change your original gameplay to try something new. Keep it up!
