Gun Build N Run

Gun Build N Run is a parkour arcade shooter centered on speed, firepower, and upgrade choices. The player controls a gun that keeps running, shooting options labeled with stats such as ATK Speed, DMG, and Range. Progress is built around choosing doors that can raise damage, shooting speed, or related attributes, so each stretch asks the player to react quickly while deciding which boost matters most. The core rhythm favors reflexive shooting and timing, but the stronger layer comes from upgrade priority. Attack speed can be valuable when faster fire helps handle pressure, while damage and range can matter when stronger shots or broader reach become more useful. Because the game ties movement and shooting together, each door choice feels less like a pause for menu management and more like part of the run itself. Motion feels smooth, and the simple stat-door format keeps the pace clear. Damage feedback could be clearer, but the changing upgrade offers make each run about adapting to the available ATK Speed, DMG, Range, and door bonuses rather than following one fixed plan.
