Thank you for your feedback.
You are totally right, we did not have enough time left, to finish the storry telling. That's something we have to do differently next time, planning :P
TBH, at first I did not even understand it myself when play testing. How to shoot faster. I could not kill the enemy's if I would not hold the button. Maybe, it would even be more fun, if we had made it, to charge the gun to a burst shot, when you hold the mouse :)
