Audio novel? interesting.
Btw i wonder what do you mean by reaching the end as the end is supposed to be something you can reach whenever you want. There's currently 7 different unique texts on the interactables (ships and islands) you can find. How many of them did you encounter? (I ask because it would help me do better games like this on the future, the way i designed everything you're supposed to find at least 4 interactables on average)
