Left Side / Right Side - Quick Pitch

Simple puzzle game for iPhone (in landscape mode), where an object appears at the top center of the screen and you swipe your finger left or right and the object flings to that side.  The game would have many different modes based on this single mechanic.  The object will fall if the player doesn't swipe one way of the other in time.  The objects move dynamically, so think, fast paces angry birds in some ways.

The game starts out with sorting the objects that appear at the top of the screen to the left and right.  if the player does not chose a left or right side, the object will fall and head toward one of the sides. Eventually, new types of objects show up, and the player will learn how to sort them so that they can keep playing the game.  It would start out with something like, just different colored blocks. get 3+ to touch, they explode and the board cascades... player learns, ok, 3+ makes them disappear.   Soon after there will be Dark colored blocks that appear in the screens left and right open areas.  these do not move.  players will learn to use the 3+ explosions to clear these blocks, as we progress, the objects change into material objects, like ice, bouncy, sticky, etc.  so they'll learn that those type need a different type of force in the fling to get them where they want to go. Eventually the player will send monsters to either side who will eat only their color block, and eventually dark colored monsters show up in static places on the left and right of the screen and the player will know to try to use the monsters to clear static dark colored monsters, and keep their board clear for more and more sorting. 

I want to teach the player the cause and affect of the objects, and then give them an opportunity to use them. They'll be challenged by the increase in reaction time to the objects as they try to keep their left and right sides clean so they can sort more objects. etc.... and i want to have these "types" of play show up randomly as the game is played, but have all the types of objects make sense with each other, so that monsters would still work on a screen filled with blocks.  This way this simple puzzle game will have lots of variety.
