Really cool concept and atmosphere, the WW2 submarine setting works great with the Enigma Machine mechanic.
Was easy to decrypt with the tutorial, the messages are coordinates for the control panel, for example NFOUR = North 4. Felt like a satisfying puzzle to crack!
That said, after inputting 10 messages nothing seemed to happen. Is that a bug or am I missing something? Would love to know if there's more to it!
