Hello, this is my completed(?) version of Orb Wars.
Basically, use WASD to move, left arrow to move left, right arrow to move right, Q is grenade, and space to shoot the laser. The laser has a heat limit, and cool-down time. The green bumps are re-spawn points, and the blue balls are the enemies. The more of them you kill, the faster they get. If they get too close you die and have to click restart. I have to say though, this is by far my favorite game I have ever made.
