Thank you for your review, i will take that into account for my future games.
The knocking sound effects are intentional in some places, but it's not supposed to play constantly on loop if that's what you're saying.
Glad to offer feedback, hopefully it didn't feel like I was just dunking on you, curious to see what you come out with next!
As for the knock, I just notice it on the odd occasion, I assume its from the other dude messing around, I only recall hearing it around 2-3 times. Its definitely effective and had me doing a double take!
