One button platformer prototype

This is a prototype of a one button platformer intended for mobile. While grounded, hold the button to charge a jump. While in the air, press the button to dash. You can dash again once you land or when you hit a wall. Holding the button down while in the air will let you begin charging another jump as soon as you land. You will move in the same direction until you hit a wall, then your direction will flip. You can either click on the button or press space. The camera is designed so that the button is always close to the player but never obscures it.
