I'm glad you liked the system, sorry if i didn't explain it well, i'll try again:
When you bump into a talker they give you a sequence of arrows and you start talking.
Now when you click on an arrow instead of moving you add that arrow to a sequence you give to the talker.
The talking stops when your sequence is the same size as the talker's sequence or if you click the stop talking button.
If your sequence is the same as the talker's sequence reading from top to bottom then the talker feels love.
Otherwise if your sentence is the same as the talker's sequence reading from bottom to top (backwards) then the talker feels hate.
