Hi (again)!
Here's a quick follow-up patch with a few extra fixes, and some quality-of-life improvements :)
I've mainly:
added sounds for the secret-related stuff
tweaked some hints in the last puzzles
decided to show the info about the cipher directly in-game after you've completed a puzzle (with optionally extra URL links to learn even more on the net). So, for the most simple ciphers you'll just get a direct explanation in the panel and for more complex/famous ones you'll also get an extra link to a Wikipedia page or an online website that explains more about this cipher :)
Stay tuned for more in the days to come - I'm sure the community still has a lot to discover... and to report to me ❤️ 😉
Cheers!
