I love this game
Coming up with your own signals feels very organic, and totally took me by (immersing!) surprise. The confusion over having accidentally made short-beep into yes was a lot more fun than it would've been otherwise, thanks to the signal being for a character who I'm communicating with (and can't amend the mistake with~!).
And the lightning parts are so intense when you've already gotten to know the character...mostly because he comes across as an actual character and not just a (calling him "faceless" would be in poor taste, so, uh) soulless wad of programming code.
Gotta say, you've got skills, man. Do good with them.
