By referencing Heidegger’s philosophical divisions from the concept of Being, the conceptual thought process constructed and realized an idea-space-time-game based on new philosophical pathways. This development went through the construction of several initial concepts, deducing their interrelations to form a spatial movement model from the contextual construction of the concepts themselves. It then used the relationships between the spatial bodies of each part as a grasping point, with the interaction modes between the parts spontaneously forming a whole. Another line of development involved incorporating elements of experience and narrative, where players, through first-person perspective integration, interactively engage with the game. This ultimately resulted in a first-person interactive experience game created with a game engine. This design and construction led to the spatial mechanism of an entire virtual world and the player’s experiential flow. Such an idea-space-time-game cannot be defined by conventional game boundaries. Its entire construction logic is born from certain revelations about ontology and even pre-ontology in philosophy, enabling a new interpretation of the game concept. Finally, it explores a new design model trinity between philosophy, aesthetics, and art. The end result is a first-person perspective artistic conceptual experimental game program, presenting a spatial relationship entity suffused with the invisibility of ideas.
