Enjoyment: I had fun playing your submission, probably not neccessary if more events were implemented, but after a while i wished for a click to complete dialog option.
Gameplay: Very straight-forward gameplay, nice thats how I like it.
Innovation: Not to sure about this one ... but I do see potential to add mechanics to add new twist to the choice have impact on available path or something similiar.
Theme: Had a similiar idea for a "tour guide in hell"-ish game, hence I agree with your application of the theme.
Visuals: Consistent art-style and solid pick for the game.
Audio: Great! Before even starting my playthrough I enjoyed the starting track.
