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.

exactly but that means that getting that high score in your game isn't as good. In the real one let's say 500 is very good but by you 1250 is like 500 in real game. (used random numbers not for sure real)
