Hey, we share some voice actors :)
Based on the quality of the sprites and overall polish, it's probably a good idea to have split this VN up into two parts to fully focus on finishing it later. The result works well as a teaser for the whole story, leaving a lot of questions unanswered.
I think it's an interesting choice to tell the story in third person, but it fits thematically with the main character being an author!
The character and especially creature designs are amazing and the backgrounds work well with the sprites. Especially the color scheme for the backgrounds just gives off this nice and wintery vibe.
In the forest where we run into that green thing (don't want to spoil anything), the background music had this high pitched instrument that seemed to be clipping a bit. Not sure if there's anything you can do about that and I also don't compose, so I'm not even sure if I heard that right.
After Eliseus' night in the village, I felt like the music was a bit too light-hearted for the scene. Not sure if that was due to time constrictions during the jam (you already had a *lot* of different themes, all things considered), but I wanted to point it out in case you overlooked that :)
Without the story being finished, I obviously can't give you full feedback, but so far I think this has good potential, with the mysteries that are being set up and a high quality basis as far as assets go.
Good luck on finishing this VN!
