if there is a smiley on both sides of the screen at once (which there usually is with so many) then you automatically lose the plane has to move faster or less smileys

all I can do is try to shoot those monsters no more to the game and you should write all the controls so people can use them. I've seen people use W A D that's how I guessed you did but arrows for moving I think makes more sense

If it's not finished then why did you upload it? How did you make the bird go out of the top with out doing removeObject() which will make it disappear not go out line at a time

not much to do in this game just moving an actor around the world. You need a timer and/or other racers and you shouldn't be able to drive anywhere you want only on track.
