thanks for the feedback! i attribute the lack of ratings to the lack of a web build in our case. we also haven't been rating many other games yet since we were recovering from the stress of the jam. (we were a bit too ambitious with this one and tired ourselves out)
i didn't think about randomizing radio placement, mainly because i wanted the players to get better by practicing levels multiple times, but perhaps randomized radio locations in hard mode would be a good idea, we didn't do that. thanks again for your kind words!
