Hi. I liked the game very much. Also, the Linux version is much appreciated.
I have some suggestions on potentially expanding the game. I'm not an expert on radio towers, but I have seen some videos on them. First, towers that high would need tethering on multiple layers, not just one. The tower in this game seems to be only structural, i.e. antennas are mounted to it, but there are also towers that are the antenna themselves. This might have some additional storytelling potential: 1) If you touch the antenna without shutting it down first, you die (and I'm sure there are multiple other ways to die if you do something wrong) 2) You would need to return to the ground for starting the Antenna up again, so on the way down someting else could happen. 3) The »doghouse« would also allow some potential for storytelling in this case (see video below). However, if the tower is the antenna, you would probably lose the ability to mount little antennas to it, but there would still be need for electronics for e.g. the lighting or lightning prevention.
You might find this video on a tower antenna inspiring:
It has a lot of details, some of which could be used for the story.
