The controls are simple. Just move around with WASD! Make sure not to touch anything red! You will have weapons orbiting you that will help keep away the red circle enemies. However, these weapons switch at intervals, so you need to change your strategy quick! How high do you think you can take your score? The darkness maybe be intimidating, but do not fear! Gems will spawn around that give you great buffs when you touch them. -Yellow gems give more speed. -Blue gems make your weapons spin faster. -Green gems make your weapons larger. -Red gems spawn a field that damages enemies. -Orange gems increase the chance to deal a critical hit. -Purple gems increase the damage of a critical hit. However, these buffs do wear off eventually, so don't get too comfortable. If you have do die, or you need to leave early, you can press space to return to the menu.
Health: The enemies change color as they take damage. 3HP is red, 2HP is orange, and 1HP is yellow. Co-op: The two player version behaves the same way, except that there is a green player 2 that moves with arrow keys, and enemies spawn 2x faster. Co-op is incompatible with mobile. Swarm: Swarm is a much harder version of solo, where enemies spawn 4x faster. But more enemies means more points! Additionally, gems will spawn in more quantities, and their effects will be amplified.
