This is a casting and voice-use detail. It does not mean that CaseOh developed, published, sponsored, or officially endorsed this fan guide.
What is confirmed
The developer, Wastyr, answered players on the official itch.io release discussion and confirmed the voice connection. The reviewed public playthroughs also contain the protagonist's spoken lines.
Is CaseOh a playable character?
You play from the perspective of the observatory watchman. Public sources support the voice connection, but this guide does not claim that the protagonist is literally CaseOh as a story character.
Is CaseOh involved in the story?
The voice is best treated as a production detail unless the game itself identifies a narrative connection. The reviewed sources do not establish one.
Did CaseOh make Out Here?
No. The official release identifies Wastyr as the game's creator. Voice use should not be confused with development or publishing credit.
