I really enjoyed the humor in the game, got some laughs out of me. I really like the contrast between the two NPC's, it helps to not make me feel excluded or discouraged by either option if at least one has a positive to say about my choice.
I would maybe provide a couple words explaing what a Geroach and Nomth individual is for people who may not be familiar, as the characters appear. Some times with fantasy, having world specific terms given to reader/player with no proper introduction or explainer can have them (me) feeling a little lost.
