Shadow Eater

Left Mouse Button - Teleport / Attack .

WSAD - Movement.

Shift - Dash.

Space - Special ability (when abiliti is charged).

Escape - Death menu / Exit Game.

Attack enemies to kill them and gather energy, additional energy charges spesial ability.

Teleporting / Attacking takest more energy that one kill can refill, kill at least two enemies to recharge some energy. 

Recharging more than maximum amount charges Special Ability.  Killing enemies with Special Ability will recharge energy but won't charge Special Ability.

Energy slowly recharges on its own, but it wont charge Special ability when it's full, so just use WSAD / Shift to move and avoid enemies.
