AppData could be a hidden folder, so you need to make it visible first.
You will get a list with in-game options:
(I list my own Gamedata below)
Explanation (as far as I can tell)
End_B / End_A – Indicates, if you have achieved Ending A or B. 1 means “yes” and 0 means “no”.
(Hint: You can get both endings in one playthrough.)
Vault – Determines, if you can access the bonus content on the main menu. 1 indicate you got only half of the options unlocked and 2 means you got it all.
Stamina – Default amount of your stamina for fruitlessly running away from things is 1000.0, increase it at your own risk.
Controls – Switch between keyboard (0) or gamepad (1)
Key_3 / Key_2 (and probably Hole) – Determines, if you have found that specific secret key (there are 3 in total). 1 means “yes, you got it, you mad man”, 0 means “No, play the game AGAIN!”
Keys – The total amount of secret keys you collected. 3 means you found them all (or you cheated, like me. :3 )
Deaths – Your death counter. Gotta catch’em all.
Subtitles – Activate subtitles with 1 and viceversa with 0.
