In games agar.io and slither.io, player control is implemented with the mouse.
The player is always in the center of the screen and moves in the direction the mouse cursor points to.
Phaser.js offers us control only through the keyboard, as there https://phaser.io/examples/v2/camera/basic-follow.
Perhaps someone already implemented control such as in agar.io and slither.io using phaser.js?
Maybe someone has code samples?
