Thanks for giving it a go! Its definitely not the most intuitive, the whole thing came together a bit haphazardly and I tend to lose myself in the art before I really have a game :)
To clarify; Scan signals to read them, and respond in the same way. Get a greeting, send a greeting back. Getting the manner right but not the precise response buys some time.
Its all a bit convoluted, :'D but thanks again for playing!
