Ratatan Development Log #7 BitSummit In the previous article, I talked about the importance of creating the UX Video for our Kickstarter campaign. From this point on, preparations for Kickstarter began in earnest. Simply making a great game would not be enough for Kickstarter to succeed. When should we announce it? Where should players first discover it? And how could we turn that initial inter…
Ratatan Development Log #5 Kickstarter as a Goal In the previous article, I talked about how Ratatan's direction finally became clear once both the gameplay concept and the visual concept came together. At this point, I'd like to clarify one important idea. A gameplay concept. A visual concept. Only when these two come together can you truly explain: "What are we making?" For us, that was the m…
Ratatan Development Log #4: Finding the Visual Concept In the previous article, I looked back on how we moved forward with prototype development before our game concept had been fully defined. However, the game concept wasn't the only thing we struggled with. There was something that demanded just as much time and attention as turning our game concept into actual game design. That was the visua…
Ratatan Development Log #3: The First Prototype Our first prototype ultimately failed. At the time, we didn't fully understand why. Looking back today and rereading the original design documents, however, the reasons have become surprisingly clear. The problem wasn't game design. Nor was it a lack of technical ability. What we lacked most was a clear core concept: What kind of experience did we…
Introduction This time, I'd like to look back at our original game proposal. At this stage, there were no gameplay screenshots, and many aspects of the game had yet to be defined. However, the proposal clearly shows what we were trying to achieve from the very beginning. Looking back at it today, it's fascinating to see both the ideas that survived and those that changed along the way. A New Ga…
Ratatan Development Log #1: The Beginning of the Project This time, I'd like to look back at how the Ratatan project first began. When people think about game development, they often imagine a straightforward process: come up with an idea, develop the game, and release it. However, the very first thing we thought about wasn't the game itself. It was: "How can we bring our own creation to player…
