Hello all, it's Cassel, developer of .It has been a while since our last development diary.Over the past few updates, we have mainly focused on relatively small-scale changes, so there were not many topics that felt substantial enough to cover in detail through a development diary.This time, however, we are preparing a slightly larger update, and we thought it would be a good opportunity to share some of our current development progress and the process behind it.In this development diary, we would like to briefly introduce how we came to plan the tourism content for the next update, as well as

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

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

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 de

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
