I'm making a pygame where the user(represented by a rocket) has to avoid crashing into obstacles(meteoroid) falling from the top of the screen by moving sideways. This is the code I have right now, I have a start screen where the user presses any keys, the game will start and there are obstacles randomly falling from the top. How do I make my rocket move sideways (left and right) using keys and to end the game(present the end screen(I have a picture)) when it gets hit by one of the obstacles? PLEASE ANSWER WITH A CODE THAT WORKS ON PYTHON VER.2.7 AND NO SPRITES! Thank you.

My code:
