# The Final Question of MU episode 1

I played this puzzle game, the last question of which leads to this website, which contains, hidden as a comment in its HTML, the following string:

OgUMGU0EHk0ZBQwZTQMCBB4ITSwqLCQjUgo=

Believing this to be a base64 encoding, I decoded it and got

: MM MM,*,\$#R

Where the first character is : and each M is preceded by one or more control characters. I'm stumped on what to do with the string at this point, and am unsure base64 decoding was the right choice.

According to this, you have to

XOR all bytes by 0x6d

to get

What is that noise AGAIN?g
