Ah ha! Then I need to bump up on the theme ;D. It wasn't very obvious so I didnt get that when I played. It also seems to me that the pool size for bullets is fixed, therefore there was one gun with yellow bullet has very short bullet lifetime if I hold the mouse - mush shorter than if I were to click. Maybe you can expand the pool size a bit if that was the problem.

Yeah it's not so obvious, I feel like a lot of people are missing that!
The bullet pool auto expands and doesn't touch objects that are active, so I'm not sure what that issue could be! If you walk forward, the bullets don't appear to move as fast and will stay on screen longer, so it's possible you're just seeing the normal end of life but moving forwards too I guess?
