No problem! One of terminals in the room, if you play with it, will help you out. Just write down the cypher and keep looking.
Also, you only need the cypher for one ending, so don't get too bogged down. :)
I hope this helps!
Thank you! I got the true ending and I'm so excited to find the cypher. Thank you for such a great game\
Really glad to hear you enjoyed it! I hope you have a fantastic day! :)
