I really like the lighting effects, really compliment the world you are trying to build with the monsters light/dark themes.
I don't think there was anything wrong with the dialogue as you suggested on discord. I think the obvious comically evil character 'D Locke' could in fact play well with the obvious Manichean light/dark themes.
The gameplay/combat itself is pretty fun (and can definitely be expanded on in cool ways beyond this jam). One thing that frustrated me a bit was getting totally jumped by surprise encounters if I clicked too far away.
Congrats on the release!
