Cool entry! This fits the theme in a literal sense quite well!
I like the gameplay that you interact and adjust with all the various knobs to achieve a goal.
I think adding a "change signals knob" in the main menu was a very good choice for the tutorial design, It's the first thing that caught my eye to try it out!
On the other hand, all the other important details were hidden in a "help folder" that took me a while to notice it's there. I think maybe a pulsing glow effect could fix that.
Lastly, unless I didn't fully understand the instructions, the signal timeout felt way too fast for me to complete the signals after the first one.
Thanks for finishing up and posting this entry! Nice little minigame! Good luck on your next project!
