Space Invaders

This is written simply by Python, very interesting to write a short game & old school. This game made us remember the old days. 

Great to make one which was played during childhood. 

Difficulty increases as you killed more enemies, and go up to higher level. 

How high your score could be ? let me know. It's hard for me to get more than 500.
