Thank you so much for the support, it really means a lot 🥹 I'm super happy you're enjoying the game. That kind of feedback keeps me going!
About the city, it was added in this version just for exploration. There's no real content there yet, but in the future it will include NPCs, interactions, and more. And I'm aware that the portal to return doesn't show up after entering the city. Since there's nothing to do there yet, I decided not to release a fix for this demo. The easiest workaround for now is to load your last save, as it always places you right before the portal.
This issue will be fixed in the next demo, which will also come with more content. I'm also planning extra versions with new features, so stay tuned 💖
