Second day of the Global Game Jam: The theme this year is "Transmission".

The game we decided to do is basically a morse code variant of Guitar Hero family of games, where instead of using a guitar to sync with notes, you would use a single key to match short dots and long dashes, trying to reproduce some mose code sequences as accurately as possible.

It was my first serious attempt at streaming, during a game jam, which means I regularly diverted my attention to answer some people's questions, discuss with the artist helping me, had to leave at some point to attend some presentation in another room, etc...

Hopefully some of you will find it interesting, but it's probably alternating between super hardcore technical details and long pauses where nothing happen.
