In the first phase of the game, click the Draw button to draw cards. You can view each card to see their effects once the Draw button is clicked. Abilities go to the bottom of the screen. At a random point, you will battle a rival cell. On your turn, click an Ability to use on the bottom of the screen. Some abilities are used only once, others use up Energy from the green bar. Usually, you will win or lose within the first three turns.
It's a bit glitchy, so I added a "Over-ride Glitch" button. SOMETIMES YOU WILL END UP WITH NO ABILITIES, IF THIS HAPPENS, JUST CLICK THE GREEN FLAG TO RESTART THE GAME.
