Unfortunately to me it seemed more like a guessing game, since there wasn't a clear pattern. And I was the only one telling the opponent something. The opponent didn't say some riddle or anything at all just told me to tell: lower or higher and it changed randomly. Eventually some dudes face showed up with hands, but that was it. I don't know what caused it, maybe I found some easter egg.
The mood was good because of the music and tho there weren't much graphics they are okay.
I hope you had fun in the game jam :)
