Very poorly thought out controls. W and S keys are on the far left side of the typical QWERTY keyboard. Arrow keys are typically close to the far right. So this requires both hands to operate. Then you need one hand for the mouse. Most people have only two hands, most people are right handed so we can either shoot or steer but not both at the same time.
So driving controls are basically pointless, this game should be categorized under Tower Defense or Stationary Shooter.
The gun doesn't turn when clicking to fire. Only by chance I discovered that it turns only when the mouse button is pressed down. So basically it is hold mouse button down all the way to be able to aim the gun. Would had been nice to put this in the instructions.
I suppose it is a decent first effort, better than many other first efforts with some graphics, sounds and no crashes but still, not really playable or fun.
