Hi, thanks for such a feedback ^_^.
I will try to add a tutorial in the next update.
What kind of hack are you referring to?
If it's a work around, then it's just rewriting words,
If you mean library, then you need to decrypt words encrypted with Caesar cipher with fixed indentation (A=d, apple = dssoh, you need to write the decrypted word on the field, for example apple),
if you are talking about the final hack on the player's PC, then you need to do the same thing as the decryption in the library, but with random indentation (it should be displayed (if not, tell me about it).
I will be releasing updates for the game in the future
bye :)
