Rust010: A step in the right or wrong direction (THEORY)

In case you haven't caught up, a user named Rust_010 has been following Albertsstuff/Flamingo for a while and making these creepy games.

W)CT
If you listen closely to the in-game soundtrack, you hear parts stopping and starting. When converted to a spectrogram, they resemble morse code. There are 2 lines of code you can hear: One representing the letter "W", and the other with the code ")CT". When WCT is converted to the vigenere cipher with the key "RUST", you get "FIB". Anyone got any theories on what W)CT is? Tell me in the comments.
