Poor
After finish the tutorial you went through to make that game you shouldn't upload your game... but simply think if you really want to make a better version which could be uploaded here...
There is a section for beta tests, demo and such lame games as yours...
It's the third time I see the exact same game with only really few art difference but with the sames bugs and colors...
P.S. You should work a way to be able to make u-turn without dying because the controls are made under if (keycode == XX) ...
you can make that by working after with while (keycode == XX) { if (keycode == something else) then do the 2nd movement...
