Hi! Sorry for this. Yes, there is a problem with messages that are too long to fit in the decrypt apps after being encrypted. I'm still thinking about the best possible solution. I had implemented a temporary workaround but it seems that it was not enough in your case. Thanks for pointing it out, and I'm glad you enjoyed the rest of the game!
Edit: I would love to ask you some information about the problem you encountered. If you could reach me at slothjam.contact@gmail.com I'd really appreciate it!
