I like the visuals, you obviously put much work into that and the result is good. Together with audio, they create a mood that fits the game concept and the jam theme really well. As for problems, I agree with other comments here. You may consider reducing the damage to the companion by how low his health is (down to zero damage if health is really low), to ensure he doesn't fall before the final duel. I also encountered a bug where, after restart, the companion was not visible, and it persisted after another restart - I had to reload the page. A skip button during intro would be nice. I also like how thoughtful the hero (or companion?) looks on the screenshots :)
