Update Game Over Screen and some crop images

Hey,

I made an update (altough the game is “finsihed”) with some more cropped images and the gameover screen is a bit updated (had only a black screen which looked a bit amateuristic)…

So this is in preparation for the downloadable version for android systems. I want to be sure this game could be played on most modern phones so I want this to be as light as possible.

Enjoy
