Thankyou so much for playing it!
Totally true, I realized too late that by default scaling is off in godot. So i always play-tested it on the window it normally opens. I did found the setting so the next update actually has scaling so people can read the letter. I heard before that the wall looked too similar so that is also getting changed. I am no musician so when i found something that sounded decent i kept it. I can totally understand it becomes too repetitive as it is like 10 seconds total. The spit is something that is indeed very prone to bugs. I tried to minimalize the chance of it by disabling movement and changing cameras so there is only a small chance it gets out of sync.
