Got some decent hours in this game, and a few things came to mind in terms of possible improvements. But just so we are clear, the game is really fun. Good combat, loot, character building, awesome spells. Generally very engaging.
Rebindable keys would be great. Having pick up items on enter is really awful, since I have to let go of WASD or my mouse to hit it. Some options for cursor appearance would be cool, the default one works but feels a bit imprecise for slinging spells. Something more like a crosshair might be ideal.
One thing I really noticed is that the energists chain lighting is CRACKED. Oh my goodness it is strong compared to other main spells. Especially if you are a human and it levels up all the time. Probably should nerf that, as entertaining as it is. Also, every now and then I enter a level with bonkers strong enemies, and stand no chance. Not sure if that is intended, could be fun if the enemies are at least not so fast I can't outrun them.
I played 1.4, so this may have been fixed, but you can walk through doors as they are opening. As in, the hitbox disappears instantly. Enemies also sometimes get close to closed doors and cast spells through them at me :/
Pathing could be a little better. Sometimes companions take longer to catch up then they should, and sometimes get caught on corners. Not a huge deal though.
Thats everything that comes to mind. Smooth sailing otherwise.

Yep, just noticed some of what I mentioned had already been addressed. Cool! Doors are always a nightmare in games XD
Maybe as an alternative to fully customizable keybinding, you could have a few different button layouts to choose from? Seems like it would be easier, but I am not a game dev so I could be wrong.
I have two ideas for chain lightning. One thing that makes it so good is that you currently dont have to aim it, since wherever it hits it arcs to the enemies. If the initial attack had to hit something for the arcs to appear at all, that would make it less powerful without making it less epic. Also, I think a damage nerf would be fine since even it did half the damage it would still be very good against crowds.
So one time I was one the third floor, regular dungeon, and there were baby wyverns, I think it was, or baby dragons, flying around everywhere, really fast. Every single enemy was one of them, and they were almost immune to my attacks 0_o If I see something like that again, I will alt-f4 and send you the save for sure. Happy to help.
