We've included various easter egg in the game. The player could check his/her process at the progress monitor on our booth, and compete with other players.
In this talk, we will introduce various feature of Rina, e.g., context-aware dialogue, achievements, rankings, message speed adjustments and async external service integration.
We will discuss our design and implementation. Using "1337 Operation" as our modal case, we will introduce how each feature could be utilized.
Besides Rina, we will also share our experience on composing the story of the game, making interactive props, and how we connect physical devices with the game.
We hope after our talk, you can also make your own real-life adventure game driven by chatbot, with ease."
