| 1.0.0530 Update | 2026-01-19 | Hello dear leaders of Ratopia!! Thank you sincerely for your patience while waiting for this update. Originally, we hoped to deliver a wide range of quality-of-life improvements. However, within a limited timeframe, we spent a great deal of time discussing which features would provide the greatest satisfaction to players if updated first. On top of that, overlapping schedules made it more challenging than expected to clearly distinguish which features could realistically be implemented within the given period. As a result, we were not able to develop as many additions as we had initially hoped. That said, each change included in this update w |

| 1.0.0510 Update | 2025-07-01 | Hello dear leaders of Ratopia!! In this patch, we've added the long-requested male Leader appearance and improved the functionality of the Porter Station. In fact, we also tried developing several additional features, such as a function to pre-warn the locations of enemy invasion tunnels, enhanced modding convenience for character appearance changes, and even a system allowing the Leader to ride animals… Though we went through numerous trials and errors, unfortunately, due to feature conflicts and technical limitations, these features could not be included. Although we can't implement every idea, we carefully review all of your feedback and u |

| Ratopia DevDiary #37 - Release preparation and Retrospective | 2025-04-01 | Hello all, it's Cassel, developer of . As with last month, we’re continuing development with a focus on convenience and polishing. With the graduation from Early Access approaching, the scale of features we can add is limited, and some new features require thorough testing, which creates a lot of time pressure and stress. We’re especially concerned that if bugs occur in new features, we might not be able to provide the best experience at the moment when the most players are engaging. There are many features we’d like to add, but with limited manpower and time, some team members have instead dedicated their efforts to planning and preparing pr |

| Ratopia DevDiary #36 - Leader Perks | 2025-03-01 | Hello all, it's Cassel, developer of . This month, I spent most of my time playtesting, polishing the game, and handling company business matters. With the official launch just around the corner, we have been conservative in adding new content. As a result, I feel like I’ve almost run out of new topics to introduce in the development log. So, for this entry, I will briefly introduce the Leader perks that will be added at the official launch and wrap it up there. Leader perk The Leader perk system was an idea conceived in the early stages of planning, but it had been so long that we had almost forgotten about its existence. When we posted an a |

| Ratopia DevDiary #35 - Religion System : Purgon Order | 2025-02-01 | Hello all, it's Cassel, developer of . This time, following the previous installment, I’d like to introduce some details about the Purgon Order and share the challenges I faced during development. The content is quite lengthy this time as well, so it might be a bit much for light reading. That said, I’ll try to mix in some -style humor to keep things from feeling too heavy. Purgon Order The Purgon Order is a religious group that worships the sun, using Purifying Lilies that bloom from deceased Ratizens to summon spirits. In contrast to the secretive atmosphere of the Umbran Circle, the Purgon Order takes a more active approach to spreading th |

| Ratopia DevDiary #34 - Religion System : Umbran religion | 2025-01-01 | Hello all, it's Cassel, developer of . This month, we focused extensively on the Shaman Leader theme. Finally, with the content now complete enough to share, I am excited to present it in this development diary. As briefly mentioned in Development Diary #32, the Shaman theme involved discussions around various ideas. Deciding how to implement these ideas in an engaging way, and determining the direction and objectives for development, was no easy task. In particular, given the diverse perspectives held by both the development team and players regarding religion, it required a careful approach to integrate and balance all these ideas within th |
| Ratopia DevDiary #33 - Intro Video | 2024-12-01 | Hello all, it's Cassel, developer of . This November, we worked on tasks related to the Shaman theme. Since development has only progressed to a prototype level for one of the two religions, Umbran, we decided it would be better to delve into topics related to Shamans after more progress has been made. As a result, we contemplated what topic to cover in this Development Diary. It occurred to us that we hadn’t yet shared details about the new intro video we worked on 2–3 months ago. So, we thought this would be a great opportunity to share the production process behind creating the intro video. Note: I am not professionally trained in screenwr |
