Lovely execution, the atmosphere was nice.

To add some depth maybe allow the operator to pick out of several messages by starting to send the first letter. Also perhaps allow sending numbers. For instance a daily report which lets you send how many troops you currently possess and allow asking for a certain number of troops or material to be sent.

While sending the game allows you to stamp on yourself, i suppose this makes it easier for those not familiar with morse code but I was practically getting a solid beep noise when I was on tempo :)

Also the background noises seemed to only happen the first two days or so? Would've been nice if those were a bit more indicative of the amount of losses.
