Easy One Touch Controls!
Your objective is simple..
Tap to Crap on passing vehicles below. Get points for hitting vehicles and extra for hitting the windshield, or maybe give the passing bird a splat! Vehicles speed up over time.
But don't get too sloppy, if a vehicle in top lane goes by without hitting = 1 miss. If you crap on the road = 1 miss. 3 misses = gameover. Hit vehicles multiple times!
* Pinpoint bird-crapping physics!
* Endless style gameplay if you're good enough!
* Compete for top scores
* Share your High Score on Facebook with touch of a button, Game Center Leaderboards
* Pause , turn off, and on will remember your progress
* Compete for Total Score or Most Vehicles Passed!
- Soon after release, two way traffic will be patched in -

Flap Tap and Crap!
---------------edit-----------------
I have updated the game but will be another week and a half before it gets through Apples review process.
I've added two way traffic, better randomization of vehicles, another vehicle, misc minor fixes- a rate and help button.
I've made TWO modes now- the one in there now where you tap to crap, AND another where you tap to fly - So it'll be two simple addicting games in one =}. I'm testing now and it works quite well.
Along with visual tutorials as if the one touch controls weren't easy enough

Keep tapping crapping and flapping!
