If you would like to reset Sneak Out game settings to default, you can do so by going to the options menu and selecting to "Reset to Default" button.
Should you have any issues with executing such, we recommend either reporting it as a bug via the in-game reporting feature (in the settings menu), or reaching out to our dev team directly or just fellow players on the Kinguin's official Discord server. You can also contact the devs directly for tech support using the kinguinstudios@kinguin.net e-mail.
