So I found a secret in Moon Omen that may or may not have been discovered yet.

The secret is actually in the background music itself. Booting up the game and going into it, you will hear a female voice saying something like "musel" in a repeating fashion as it fades in/out while this odd mechanical noise goes on continously. At first you would expect it to be nothing, but turns out that noise is actually a heavily distorted voice. Here's how I found out:

- take the music from the thing ("game") and extract it into an audio file (record it, dig into the files etc.)

- put it into an audio editor (I used FLS, but you can use Audacity or any other audio editing software.)

At the part where the voice fades in and the noise (mechanical sound) plays for a second, pauses, then you hear it click, select the beginning section from when the voice fades in to when it fades out. You will know where to end the section as there will be a strange almost "bubbling water"-like sound fading in as the musel voice fades out. (For the extracted audio, it should start at 16 seconds and end at the 21 mark.)

Next what you want to do first is raise the pitch and speed of that section, and I mean speed it up to where it sounds like the voice is repeating at a fast rate and sounds like a chipmunk (it will sound like the voice is laughing.) 

Afterwards, you may hear the noise finally become somewhat audible as a distorted voice.

If you're still having a hard time hearing it, try changing the pitch and speed to a higher degree. Denoising the musel voice layered on top and the music helps a lot too. Just tweak with the denoiser until the distorted, mechanical noise is clear and little to no background noise is audible.

Here's what I could hear from the voice:

"The storks see me" *screeching noise* ("I see them")? *more noise*

The voice also seems to say something else, but it's too distorted for me to understand.

Wonder what else there is we haven't found yet in UD's old games? Anyway, hope this helps (and makes sense)!
