The ball not lowering for shield recharge is a bug that I could not reproduce in Unity and so I wasted a lot of time with trying to fix that.
The Signal detector was intended to provide Voice Overs which would tell the story but time ran out and I dont want to cheat so I will provide the missing rest after jam submissions are over.
The core idea was, that you only can activate a maximum of two pedastals at the same time. With that rule, that game might have been more interesting but my main focus was to find a way that synchronizes the sounds.
