Interesting concept, a bit klanky, but the graphics reminded me of the old Doom and Wolfenstein games, cool!
Though sometimes I saw a message with no text, just a dot in it ".", not sure if that is by design. And also first time I played - I faced a weird behavior, I had 1200 gold(around that amount), faced my first eye-faced, and after giving him around 50 gold - I received like a gameOver message saying I didn't get enough money to feed my family, not sure why. And when I clicked restart, it kind of continue from the same spot I stopped on so I continue playing.
Overall, fun concept, simple but catchy, need a bit of polishing, interesting!
