Mouthwashing, an indie psychological horror game developed by Wrong Organ and published by Critical Reflex, was released on September 26, 2024, and has since garnered critical acclaim, earning accolades including Best Narrative at The Horror Game Awards (2024), Players’ Choice at the same event, and a nomination for Outstanding Achievement in an Independent Game at the DICE Awards (28th Annual).
