"Keep it bouncing" 
 
An app about keeping a ball bouncing and trying to make as much distance with it as possible. Certain powerups when struck by the ball will cause it to speed up, slow down, or change it's arch of movement. Some will stop the ball altogether ending the game! This is a game which will generate a lot of press buzz because it plays similarly to  "Canabalt" in that it only has ONE BUTTON to do everything!
When the ball is moving in an upward arch, touching anywhere on the screen knocks the ball down. This ability recharges every 10 seconds!
When the ball is in a downward motion touching the screen will make it get knocked upward and to the right!
This ability can only be used 3 times.
The types of powerups you hit: (These are randomly generated, equally spaced apart, and they slide from the right side of the screen to the left.)
At the start of the game you have 2 things you have to press the screen for.  First you press for the angle. An arrow archs back and forth between a straight-right and 75 degree angle to the right.
When you tap the screen the arrow freezes at the point it was bouncing toward. Ideally you want it in the middle range. We can color these areas yellow, green, and red as needed for "Ideal" vs "bad" starting angles.
After you pick your angle a power bar starts raising up and down.
Tap the screen (anywhere on the screen) and your power is selected.  (This is actually the first screen there's no title screen).
After tapping at your selected power level your ball is lauched at the angle which corresponds to the power level. Below you, as you bounce, you can see various colored power ups with different abilities passing by. 

We'll try to either have interesting charachters or symbols with colors to represent
abilities, powerups, techniques, etc... The thing you keep bouncing could have a face, though.
Here's the power ups:
GOOD Powerups:
Purple Power Up: Bounce Higher -  This causes your arch to shoot almost straight up at a 65% angle, it hurts your ability to earn points by making your angle more verticle, but it could save you if your ball is running low.
Green Power Up: This is the best one. It knocks your ball farther at a 45 degree upward angle! WHOOSH like a baseball getting hit out of the park!
Blue: Very Powerfull Hit! But it's almost horizontal! Close to a 25 Degree angle (rather than the 45 angle of green) great speed and power!
NEGATIVE / COMBO Powerups:
Black: SKIP!  This one does nothing, But as you touch it, it fades to the right.  The next powerup you hit, this appears in front of and BLOCKS IT.  This can be good, or bad!
Red: This is an immediate stop! The worst kind of power up! You lose!
JUST AWFUL Powerups:
Yellow: Slow Down!!  Oh dear, this one slows your ball's speed by 50%. May help or hurt you depending.
Brown: Change Angle!  - Uh oh! If you're bouncing at a degree higher than 45 degrees you switch to a 25 degree flight at your same speed! (no speed boost)
             &n bsp;  If you're bouncing at a degree LOWER than 45 degrees you suddenly start flying at an 80 degree angle! Uh oh! (no speed boost)

User Controlled Powerups:
Once again remember that touching the screen at any time during this will be able to influence your motion.
On screen you have 1 powerup with a cyan arrow pointing up and to the right at a 45 degree angle. next to it is a % number.  When it's at 100% you can use it.  It takes 10 seconds to recharge.
The next is the 3 "POWER" arrows. These are orange in color and aim down and to the right at a 45 Degree angle. You get 3 of these. As you use them the arrows dissapear. So after 3, you run out! That's it!
 
The objective of the game is to stay airborne as long as possible and make as much distance to the right as you can! 
Distance is measured in the top right corner of the screen. And we might have this link to an online high score board!

C-C-C-C-COMBOS!!!
TWO BLUE- It's oh-so-true. Two blues sends you flying in to the wild blue yonder increasing your movement speed by 300% This rare chance of hitting 2 blues in a row means you get tripple what the boost would have been! WHOOSH!
Purple + Green (Or Green+Purple! Combo Saver!)  On the rare chance of hitting a purple then a green you get a "safety" powerup in the top right corner. When you hit a yellow, brown, or red powerup, instead of the usual effect, purple + green
powerups will appear and it will say "GET OUT OF BAD-LUCK FREE!" as you are then sent upward at a 45 degree angle at 200% your current speed.
B-B-B-BREAKER -  Hita purple, a green, and a blue in any order just once and you get a B-B-B-Breaker Boost! This means if you hit a Red powerup your speed will be increased to the absolute maximum and you will be sent up and to the right at a 45 degree angle. This move is especially hard to do because the effect is disabled WHENEVER YOU BOUNCE OFF THE GROUND.  So if you hit the ground before hitting the red, you automatically lose.


What a Tweest! - You just hit two yellows in a row, and then a brown! This technically should be the end for you. But what's this? A power bar appears and it's like you're launching yourself all over again! A Fresh start, just when it 
seemed like it was going to be over!?  Hurray!
