I just need a simple working game with an explanation of the codes in comments so that i can re-use it for my own project. I need a game with a player with images provided, enemies, projectiles to kill the enemy, and a item on the map that will trigger a quiz. Wrong answer given will summon a flying enemy chasing the player until the player reached the end point. Flying enemy should be able to go through the platforms. Since it's a platform game, simple platform will be needed so I can learn. Please do not make a lengthy coding game. And graphics should be reasonable and not just a square or rectangle.
