This ain't much, just a small test I am doing. I may add a lot more to this including better graphics, moving enemies, and a lot more if people like it. I just don't want to waste my time if no one likes it cause i know completing it will take a long time.
Anyway, push shift to zoom in and Control to zoom out. Fire with the mouse.
and obviously you can't win or lose yet so don't play for too long.
