Thank you for the kind feedback :)
I tried to implement the sfx better a few times but this was the best I could do. But, I'll get better at it I hope
And, yes the gun's collision does make aiming in the close range difficult and I also struggled with it in the playthrough video. But, it was necessary to add the gun collision to stop player from shooting through walls.
Again, thanks for playing my game and I am glad you enjoyed it :)
