It would make for a good red herring to keep them, but let them lead to other clues. Good job on the game! I definitely had to play long enough to make it to the end, though had to use your guide because I kept getting it wrong :P
Thank you very much for playing and for your feedback! The update is coming but still needs a few more features and playtests before I publish it :P I added an in-game help/guide, we'll see if it works or not. As for the red herring, it is a very good idea, but I think I will keep this game quite short and not add too many content, it is just a jam game after all ^^ I'll keep this in mind for future games maybe ;)
