The reason for that is that it works like a real revolver. If there are empty shells in between shots and you pull the trigger on an empty shell it won't fire.
Yeah we originally had the guns a little closer to the player and lower but we wanted to make sure everyone would be able to reach them. It would be better if they were configurable or something perhaps.
And yep about the standing and shooting, we talked about adding in obstacles to duck under like you see in some movies and other games but we did kind of want it to be playable sitting down.
Thanks for playing!
