Thank you for your feedback and for sticking through and playing later levels! The mechanic at play is the red signal that goes out when a satellite is launched triggers any existing satellites it reaches to self-destruct and any objectives the signal reaches are reset. But if a satellite or objective is in the shadow of a planet where the signal can’t reach it won’t be destroyed/reset. That is what we were trying to teach in levels 3 and 4 but I don’t think those levels succeeded in communicating the mechanic like we hoped.
