I'm very happy to hear that you enjoyed the game! 👍
And thank you for taking the time to write this nice message. 🙂
There will be new content in the future. The game is constantly being updated (new updates every month) ☺️
You don't need to do anything, just install the new version and your saves should be there.
There is a faq on my discord server, feel free to check it out if you have any more questions! 👌
