Ok, I swore this would never happen again but I'm someone who doesn't learn from mistakes until I make them several times I guess... thanks for informing me of the problem! and on the radio you have to press the "E" key to change there are only 4 modes "music box", "rain", "music box and rain" and silence, and about Sonic.esex(Eris) I don't think I'll add it soon, I must improve and polish slenderwoman first to deliver a good playable level but I hope to do it as soon as possible.
(Uninstall and reinstall the game to apply changes) Thanks for playing and commenting!
