Good start for a first game! Getting the portal to the ghost town was a bit of a challenge, and it really does feel like a strange place. Being able to interact with several NPCs was cool too. It’s a bit rough around the edges, but it definitely has solid potential, it made me curious about how the progression might develop. Nice job though!
Also, I noticed the game is currently uploaded as a downloadable zip, but it seems like it’s actually a web build. You might want to upload that zip as an HTML game and enable “This file will be played in the browser” on itch.io so people can play it directly on the page after the jam is over.
