Ooooh, this one really was a pleasant surprise. ^^
Something about this game felt so organic and nice. Even as somebody who doesn't know much about sign language, maybe two or three words, I was able figured it out. :D Such a creative interpretation of the theme. I would so love to see more of this, maybe even with more complex puzzles that require cross-examination and listening to multiple NPCs before judging. :D
Great job guys! ^^
