Dufajio Barn Rush executes a designated splash screen during its startup sequence. Following the loading phase, the root menu is displayed, providing access pathways to the main operational module, a maximum performance tracking table, an avatar customization interface, and system configurations. A separate questionnaire module is also accessible from the interface to evaluate operator knowledge.

The core simulation places the operator in control of an avian unit moving through a simulated cosmic environment. The software continuously generates physical obstructions along the flight path. The operator must provide rapid directional inputs to maintain the avatar's trajectory and evade physical contact with these obstructions. Simultaneously, the user must intercept and accumulate specific generated items scattered throughout the environment. The primary operational directive of Dufajio Barn Rush is to maximize both the continuous distance traveled and the volume of items gathered.

The items aggregated during the simulation phase are utilized within the customization interface to unlock various visual profiles for the avian unit. The software permanently logs maximum traversal metrics and item totals, presenting them on a dedicated ranking table for historical comparative analysis.

An independent settings dialog in Dufajio Barn Rush permits the operator to toggle acoustic outputs, clear all saved progression data from the application, or return to the root menu. If the avian unit collides with an obstruction, the session halts, and a terminal interface is rendered. This specific dialog presents structural options to resume the interrupted trajectory, restart the spatial simulation from the beginning, or navigate back to the root menu.
