Oooh, very nice interactive project. I wonder how it judges my terrible drawings haha.
Though I don't know how much is it a "game" in a sense. I had fun drawing the different things with the challenge imposed on it, but since there's not really a "fail" state, or something else to compel me to do well, it fell a bit flat. If there was some gamey elements to it like you fail after not reaching enough scores after some numbers of drawings or something then I can see it be much more interesting to play.
I still had a bit of fun with it though :)
