Game title: Vertix.io
The family of io games is constantly growing and new genres keep appearing every other day. Vertix.io is one of the early shooters that launched under this title. In this game you have to control a player equipped with a gun standing on a 2D platform and aim at your opponents. Your character moves when you press WASD keys while shooting is performed with left mouse button. Use the scroll wheel to change weapons. The trick is to keep the mouse arrow moving near the screen edges. This way you can expand your range of vision and get the upper hand over other players who are unaware of this strategy. Try to outlive your rivals and remain unharmed!
