Purple Gem Ring : MM06
You pressed the correct button.
It appears that the number represents how many times the letter appears in the word.
In Like, k appears once, so it is k1.
In Share, a appears once, so it is a1.
In Comment, the letter that appears twice is m.
Therefore, the correct code was m2.
You press the m button beneath the frame.
Moments later, a section of the wall beneath the buttons slides open,
revealing a treasure inside—a ring set with a purple gem.
You reach into the small hidden compartment and retrieve the treasure.
After securing the treasure, you leave the area.
You have successfully escaped.
You have secured the treasure.
Congratulations!
