The document describes the development process of a game created by the authors. It began with research that inspired a stick figure character design and ninjas as antagonists. An agent was chosen as the protagonist to wipe out the ninjas. Concept art and planning established the endless runner genre and warehouse setting. Production involved dividing roles and implementing graphics, sound, and coding over 3 weeks. Post-production focused on debugging numerous glitches. Feedback after publication was mixed, with regular gamers enjoying it more than casual players.
