The 2D and 3D hybrid techniques had primarily been employed in films in the animation industry. However, the 2D and 3D hybrid techniques are not just for animated films as they may create assets and environments for video games. Game animation, like film animation, has progressed from 2D to 3D techniques. Furthermore, while a few research and current systems have used interactive storytelling in mobile applications, none has included Augmented Reality (AR) as a feature. The goal of this research was to generally create Adventures of Tammy: Play your Stories, an Interactive Storytelling Mobile Game with Augmented Reality Story Playback. The app was successfully developed through Unity, ARCore, and ARFoundation. A survey was conducted last November 8 and 9, 2021, and administered through the use of Jotform and Google Forms to gather responses from 15 children as target users, 5 basic education teachers, and 5 functionality testers. It was a non-probability survey and it focused on the 5-point Likert Scale with Very Good, Good, Fair, Poor, Very Poor rating. This study used a mode measure of central tendency; obtaining the most frequent answer—or the mode—per question. Based on the survey results, the objectives of the study were successfully achieved. The proponents were able to develop assets and environments using 2D and 3D hybrid techniques, to implement the developed 2D and 3D hybrid assets and environment, to produce a visually appealing app for children, and to embed an AR technology used for the AR story playback.
