Really struggled to work out what to do, maybe you could post a few clues so I can give it another go because there seems to be more to the game than I was able to find. Will refrain from rating until then.

Hint for the first puzzle would be that the roman numerals below the slots are buttons that select the number currently in the slot above. Also 00 = 1 and, 11 = 4. If you're having trouble with the early game loop. It's just open messages->tune the radio (circular panel top right)->initialise radio with button-> puzzle icon should light up on desktop, click to open puzzle. I hope this helps! We're hoping to do some further work after the ceremony for the jam so the goal is to guide the player just a bit more. Thank you so much for your feedback! - Mystic
