Can't press "?" (The Key Code Thread)

Does this game have any sort of lore?

Important for Devs: Age Rating! [Please Read!]

Achievement descriptions?

Stuck at "TYUGHB".

The song at the second frequency puzzle

Unable to get achievements

Well that was.... interesting.

Damn game bugged out right at the end, so now I'm stuck walking forever on the final puzzle.

Stuck underground at the 4 "dong" sounds + mouse scroll place

Will the game be expanded?

Loved this game

First level

Waste of everyone's time

It's so unclear what I have to do...
