Lastly, I added effects to the tornado itself. The game object rotates at a rate that seems consistent with several tornado videos I watched on YouTube. I added a simple cone-shaped particle system at the base of the tornado, and am merely rotating it at a speed that is faster than that of the tornado itself, giving the effect of fast moving debris. I'll need to spend some time on YouTube watching tornado clips to get it just right, but for now, it does what I need it to.
As you can see from the previous screenshots, and the video below, the basic concept and mechanics of the game are becoming apparent. Different animals are suspended in the tornados vortex and you drag to match species (ie. cow, pig, etc.) and save them. I am anxious to begin modeling the animals, but I need to have proof of concept done before too much time is spent on assets. The game may not be practical, or may fail as far as gameplay experience and entertainment value. In short, it might not be a fun game to play. I'm pretty confident it will be, but only time will tell. That's why proof-of-concept is #1 on my list right now... to get a version done that I can play, to ensure that you feel you are getting progressively better at the mechanics as you go, but still being a game that you can never be perfect at. You'll (in theory) always have the opportunity to beat your last high score, which adds replay value.
Next step is to take my 2D game mechanics I have done for a previous game and convert them to work with 3D objects. Once that is completed then a scoring system will be put in a place, and the game will be, for all intents and purposes, playable.
Edit: One final thought, I want to give credit where it is due. The barrels seen in the screens/video were downloaded from Unity3D's Asset Store. You can find them here:
