I really would have liked more story, more fleshed-out supporting characters for him to interact with (more chance to be a smartassing badass when people with personalities are there to mess with), and lots more puzzles. It felt like there were more cutscenes than gameplay. Also...could take the misogyny down a notch...or ten. Misogyny =/= badassery. It's more like "douchery." Enjoyed some of the little things though: kitty of doom, guards with dolls, and sunglasses flying off only to return perfectly.
I really love brain teaser games like this--my first was Discworld back when I was little. I'd love to sit down and take the time to pick apart various psychological quirks in dear little Belial from this chapter...poor guy has some issues.
