This was an interesting concept!! I LOVE how the signals/vibes poped out with their colors!!
I think it was a tiny bit repetitive, I liked how calm it was but it also made it low stakes. Maybe in this direction, it would have worked better if you had to send actual answers between ships (kinda relaying information or lies between nations) for a narrative aspect!
Otherwise, maybe if there were tons of ships that were coming by faster and faster until you send the wrong signal and got destroyed (then u can compare you score with people).
Nice job still!! I’m very impressed by the UI, it clicked pretty fast, even though you had like 30 pixels to work with haha!!
