Really nice Diablo 1 feel on this one! Weapon skills is a good improvement on the formula and was something D1 really lacked. I did encounter some bugs, most very minor though. You are probably aware of most of my suggestions already.
What items get auto-equipped when picking up seems inconsistent, gloves for example did not equip but most others seem to.
Changing the volume in the main menu didn't change the volume of sounds from the main menu.
The Resume button in the esc menu doesn't do anything.
Cult Apprentices not outlined properly.
Dying while poisoned and loading a save - still poisoned.
I got a lot of holes in the automap where there were walls.
Right clicking on potions dropping them instead of drinking was a bit annoying when shit hit the fan hehe.
Outlines for doors when hovering over them would be nice.
Options for a transparent automap and having it in the corner would be good.
Shift clicking with a melee would should let you swing at the air I think.
All in all it seems really promising, great job.
