Grid Shot

Controller: Right stick to move and left stick to fire in the indicated direction.
Keyboard: Arrow keys to move and WASD to indicate firing direction.
On screen joysticks: The right one  to move and the left to indicate firing direction.

The first level has 3 bad guys. Get all of them to finish each level. One is added for each level attained up to 28. If your player gets hit by a bullet, it will get moved to a random location in the grid and a new Enemy will be placed randomly. If there is nowhere to place the new Enemy, it's Game Over.

You get points for finishing levels and hitting Enemies. You lose points for each shot fired and for getting hit. A Timer is running on the right side. It starts at a value that is higher for each level attained. At the end of the level you will get points for any time remaining on the timer and lose points if the Timer value is less than zero. Your Score can never go below zero, but if it is at zero when the level is completed, it's Game Over.

You win if you get through level 28.
