Echo Gun

Welcome to "Echo Gun" — a vertical adventure that defies the common laws of physics.

In this game, you are no longer a gun-wielding warrior, but a handgun imbued with anti-gravity magic. It doesn’t shoot bullets to attack enemies; instead, it uses the recoil from firing to continuously propel itself upward.

Gameplay
You need to carefully observe the rotational inertia of the gun barrel. Only when the barrel points directly downward should you pull the trigger, allowing the recoil to push the gun upward. Firing at the wrong moment will cause the gun to lose control and veer off course.

During your ascent, you need to collect glowing ammo boxes to replenish your bullets while avoiding obstacles. The journey ends if you run out of bullets or fall off the bottom of the screen.

Game Features
Unique rotational inertia: The handgun swings like a pendulum, and you must anticipate and seize the fleeting "golden angle."

Progressive tension: As you climb higher, the gun’s rotation speed increases, and obstacles become denser, pushing your reflexes to the limit.

Endless challenge: There’s no finish line, only constantly refreshed height records. Every failure is a chance to gain experience for the next trigger pull.

Pull the trigger and defy gravity. How high can you challenge the sky? Every successful rise is a victory over the laws of physics.
