Interesting game, still not sure how that fits the theme but good work none the less.
Also, the combinations for the Yes No were pretty tedious to go through all of them and difficult to memorize. I would maybe try a different input method, for instance, using the keyboard for each finger, lets say QWERT for left hand and UIOP for right hand and have all the possible signs on the wall at all times.
I think that would really make the game faster and more intuitive.
I think this game has a lot of potential, great work for a 48 hour jam. I hope you have some time to review my game.
Kudos.
