To all the medal whores out there:
The goal of this game is to hit the American Flag and nothing else. Things that will get in the way of doing this are:
Planes - Fly in a straight line at you
Helicopters - Fly on an angle forever
Birds - Fly on an angle, but will BOUNCE BACK when they reach the upper or lower limits
Yes, they are white, same as the clouds. But once you see their flight path, you don't have to be Donald Duck in Mathamagic Land to guess where they're going and successfully avoid them. There are no instructions, and the 8 bit graphics/sound are because Nene was deported and she made this in China.
Two things I would change, though:
Random spawning - make a safe zone when you start a new level. It's been said before but it's not sporting when an enemy hits you before you can move.
Front/back movement - there are some instances where the shoe is so big a single bird can take it out with the right angle and you have nowhere to move (up/down) that won't kill you.
The challenge is in the achievements, but honestly, that's the only reason I would play this game more than once.
