Ugh. Meant to comment here and not the game page!
I was extremely confused because I started the game and stepped away. When I returned, I’d missed the initial story bit completely and was in the first signal UI. Assuming I’d missed something, I refreshed the page to start again and went straight into the signal UI. Nevertheless I finished and later figured out to reset the game from the options menu to get the initial story.
Anyway, excellent UI and good interpretation of the theme. You could just release the spirograph part as a toy and it would be amazing!
