I love the graphics and music! I think the main thing that could be improved is making the UI cleaner. For example, on the control change menu, instead of showing "move_left", you could remove the underscore, or just make the text say "left". Also, if the options menu is open and you press options again, it opens up another instance of it, and this can stack up. I also agree with what shpil said about the number sticking to 2 decimal points when leaving the signal radius. I think it would also be good to note that when starting the game, if you spend your resources poorly (not using all your resources on the drills), the game starts off extremely slow and can take a while to reach a pace where you can start collecting resources and build buildings with ease. Also, this might just be a me issue, but I think the range where you could place the first antenna could be bigger. When I first played, I couldn't get the introduction to go past where it tells you to place the antenna, because I couldn't pinpoint the exact location of where to place it. I did play without a headset, so maybe that made it a bit worse for me. Overall, I think this was a good game! It fits the theme well, and it's really nice to look at. Audio and SFX also fit really well. Great job!
