Nullpulse Runner

Gameplay and controls are designed for keyboard and mouse input. The player character moves forward automatically at a constant speed. The primary control is the mouse, used to steer the Runner left or right by moving the cursor horizontally across the screen. The character follows the cursor’s position relative to the center of the playfield. To jump, the player presses the spacebar. A single press initiates a jump; holding the spacebar does not extend the jump duration. The jump height and distance are fixed. To perform a slide, the player presses the left Shift key. Sliding reduces the character’s hitbox height, allowing passage under low-hanging obstacles. The slide lasts for a fixed duration of 0.5 seconds and cannot be canceled early. The game does not feature a pause function; any interruption of input results in an immediate collision and run termination. The interface displays a single numerical counter in the upper-left corner, indicating the distance traveled in arbitrary units. A red warning indicator flashes at the screen’s edge when an obstacle is within 0.3 seconds of impact. No tutorial or training mode is provided; all mechanics must be learned through repeated play. The game offers no difficulty settings, accessibility options, or control remapping.
