Yeah there is, there's one letter for each ending (A to G), you just need to work out what they all spell and where you use it
wait is this something like you get the word then you put it as your name and get a secret ending? If so i really need to finish the game
Not a secret ending exactly, but yes there are some extras hidden behind it
How exactly do we know if we have the right word? Will we know immediately?
Yeah, you just need to type in the word into the text field and hit "Time to get started".
If it proceeds as normal, you haven't got the right codeword yet. (Do bear in mind, it is case sensitive.)
