Hey I gave it a shot, I will work on it later. For some reason if you shoot from the right side it removes bullet, but if you shoot from the left side it removes the guard. Weird.

Good game. I would greatly appreciate it if you could share how you put the timer in the top left corner. I am trying to do something exactly like that, and I have not the slightest idea where to start. Basically the visual part of the counter. If you could share some knowledge :]
