Looks like a huge game and it has his charm, I like the atmosphere but i could not advance after the first boss because on my laptop the game has slowdowns on the second tier of dungeons.
I have the feeling that the melee attack would work better if you divide the attack in 2 phases, hold button to charge and release to swing i feel it was too much slow for bigger weapon to actual attack, also i think that the hot key bar need to be revisited, if i put a weapon in a slot after selecting should stay on that slot.
Enemies are too goofy, I have the feeling that this game will not work if there is such contrast between the ambience and the screaming goats for example.
also it would be nicer if you have more telegraphic attack, the lighting strike seems to random and sometime hits the enemies, i feel that in this kind of game you want to master and manipulate the situations.
Also everything is gray and i feel that need more balance, i get that you want to give a claustofrobic tone but the HUD for example could benefit for more vibrant color.
