Suggestion: adjust walking speed

I would really like to play this game, but spending even a few minutes playing the tutorial made me extremely nauseous. The movement speed was way too fast, and at least for me, the key that looks like it should change the walking speed doesn't actually do anything. I know it's a pirate game, but I would like to play it without getting seasick. Is there a way you could add a motion-sickness mode or something for those that have that issue?
