Very cool gameplay! I played until level 3 before I lost. I would say one thing, it should maybe be visible when a signal is about to expire (a timer pie icon or something) because it happened that I was trying to finish the topmost request, and it kept expiring right before I could finish it. And then I end up in a chase where I do the next one, but then that one also expires before I finish it.
It'd be handy to see like "oh, I know I'm not gonna make that, I'll move on to the second one in the list".
I like the animations of the main character lol, good job overall!
