This mod turns your stardew valley farmer into Siren Head! Check it out! Was created by me: https://www.nexusmods.com/stardewvalley/mods/6061?tab=description
Well it looks real creepy. I recently learned about siren head from an interview on techlater.com and was very interested in this character. Have you thought about developing this mod? For example, add various strange sounds. Hmm .. I have one crazy idea, but I don't know if it can be implemented. For example, you can ask the player to record the voices of his friends and family. Then, using computer processing and recorded voices, generate creep phrases that will randomly sound during the game. Also, you can, for example, make that every fifth notification of the game will sound exactly with these voices. I understand that this is very difficult to implement, but it would look very cool.
