<Ratopia> will continue to receive updates even after its official release. We will monitor user suggestions and feedback through the community and actively reflect them whenever possible. You can expect ongoing support in various areas such as bug fixes, balancing, text refinement, and system improvements. We also plan to gradually add new content to enhance the game’s completeness, so long as it doesn’t interfere with the overall game flow.

We are also planning improvements for Steam Deck and console environments. Due to issues with text size on certain screens, <Ratopia> did not receive the “Great Experience” mark on Steam Deck. However, we will continue to improve readability and platform optimization so that more users can enjoy a comfortable experience.



Join the Steam discussion board and the Official Discord[discord.com] to share your thoughts with fellow Leaders. These two communities are the ones we monitor most actively and use to gather feedback, so feel free to share stories about your city and gameplay experiences, or leave your valuable suggestions for improvement at any time.
Watching you enjoy the game is truly the biggest reason we created <Ratopia> and continue to support it.



There was once a child who loved city-building games.
As time passed, that child dreamed of becoming a game developer, hoping to share the joy they once felt with others.
But making a game turned out to be far more complicated and difficult than imagined.
There were moments when progress had to stop in the face of countless problems, moments of accepting imperfections, and times of necessary compromise.
Being a developer often meant confronting oneself.

Even through such times, we were able to keep moving forward—because of your support and encouragement.
Your heartfelt messages, warm words, and even sharp feedback—all of it came together to make <Ratopia> a reality.
To everyone who has been with us for over three years, we offer our deepest thanks.
<Ratopia> is a game shaped by your participation and your patience.
We sincerely hope it becomes a joyful memory for you.

We also ask that you continue to support and encourage indie developers, just as you always have, so they too may create even better games.
Thank you.

Sincerely,
All of us at Cassel Games
