Hey there! Paradise Station, and Space Station 13, can have some scary game modes and antagonists, so it might not be your type of game, and that's perfectly fine, alright? Feel free to try it as much as you feel comfortable, and as long as you are playing non-Command and non-Security roles, and not a team Antagonist like a Cultist or a Shadowling, if anything gets to be too much for you, you can just close the game window. And with that being said, if you're confused or unsure, feel free to use adminhelp or mentorhelp for help and clarification.
Most noises you don't like can be disabled, alright? If you don't like the ambient noises (the background noises the game plays to make it feel more real for players), try checking your Preferences tab to click Hear/Silence Ambience. Clicking on Hear/Silence Midis can stop you from hearing music/sounds uploaded by admins, as well, which can be startling for some players. As well as this, if the AI's voice is a bit too grating, you can click Hear/Silence AI Voice Announcements, and that'll turn those voice announcements into text so you can just read them instead.
Take as much time to learn as you need, reach out for help as much as you need, and know that you're welcome as long as you'd like to stay!
