First off, congratulations on completing your first game jam game and for doing it solo too! This was my first time making a game solo and I can now appreciate just how much more work there is to do.
I think you wisely chose a good-sized scope for your game that is relatively simple in terms of game mechanics, but allowed you to focus on the experience via your artwork and narrative which were both excellent. This town had a cohesive quirkiness to it that made it fun to speak with the locals and fit within the story.
I can see the delivery puzzle that appears to exist and presume it would result in a "good" ending, but unfortunately I was unable to figure out how to complete it. I suspect the first step was related to collecting the hot peppers, but the best I could seem to do is see the text box "hot peppers". Despite being unable to figure out how to achieve that, it was still a great experience and you should be proud of your first game jam game.
