You art is cute l love it! And this is a really interesting version of rock paper scissors. But I would say that adding some background music would be more amusing during the gameplay, maybe street noise or a lively tune, whatever kind of music. And besides this, it is a little bit hard to figure out the time limit here since it is represented by words, and therefore it makes me confused about when is the final time I can still change my decision. Maybe a graphic indicator would do the work. Great game overall!
