I'll have to play it a little more extensively to check on it. I'll do some experiments! :D
Edit: So I did some testing and there is just a "dead-zone" in the middle right area of the screen. You can test this at any time by firing the gun into that area, there is just no bullets coming from the "gun." I hope this helps.
Btw, I forgot to mention, I love that you have multiple paths like that, great addition!
