Instructions
You control a red character with two guns at either side. Thus, when aiming directly at an enemy, the bullets will shoot to the right and left of it.
Shooting will cause a recoil effect, where if you recoil out of the designated floor, you will fail the level. The game shows both the amount of enemies needed to kill, and the amount of shots left (as opposed to how many bullets).
To aim, drag your finger in the opposite direction of your shot (shown by a red point inside of a white circle). The levels evolve by having to reverse onto jump pads, walls obstructing your path, and grass obscuring your view.
