Space shoot em up game using Pygame
Message:
Create a game using python pygame ..and make the ( space shooter ) game.
Also to write a report and making a report that provide:
brief description of aim analyse of requirement of program
design – document of flow chart
testing – tables of test to be under taken to prove that program achieve its goals
Critique – what worked and what didn’t work.
