Normally I don't like this type of game but I actually enjoed this. I liked the style in which it was presented and I liked the way in which the predictions were presented. For those who don't quite seem to get how this works:
If the colors do not match it is like when a magic ball tells o "it is uncertain" or 'try again later". It is not a no or a yes.
Unlike many 'fortune' games this does not rely on yes or no questions, or yes or no answers. It gives a 'feeling' for an answer. This alows some interpritation by you of the answer. But not only does it give you a feeling or loose interpretable answer it also gives you a sureness level, based on how quickly it responds to your question.
Really as far as fortune telling games it is brilliantly set up, and so simple.
Back to the author, I did notice one bug durrning the game. There would be times when one flower would not visually change color, but even if the final visible colors matched it would not return a match (suggesting that the visuals are glitching a little). It was not a regular glitch and always seemed to work the next click anyhow. Just thought I would pass that on.
Keep up the interesting creative work.
