And also there's a feature (not a glitch/bug)
In story mode, endless, ultimate, and also customizer if you reach any exits. The light is black and also, if you are in harder/difficult maps. It will make it imposibble to see but this feature must have a option but. If you ready to play harder/difficult customizer maps this option must be disabled/turned off so the light will be Red instead the lights off/being dark please add this option Johnster!
