Hi, I downloaded the newest version and for some reason whenever I move/interact in any way, the starting gun (can't remember its name but it sort of stabs out with a spike) 'fires'/makes a noise. I guess this could be down to remapping keys, since it didn't happen before when playing the vanilla release.
That's strange... Do you have a middle mouse button or mouse wheel? That is what the blade is mapped to by default, so if you don't have one it may be that it is retrieving a key code that is mapped to something else entirely, and its confusing the game. You may need to set it to something else in the control options, like Spacebar.
