A summary of the way everything is programmed in Contra. Really neat to see how things are set up into structures of arrays and how screen space is managed, etc. From a game design perspective, also very interesting to see how they programmed and balanced the randomized enemies. Gotta test those reflexes with some random elements, after all. Changing the hitbox of hazards based on players current movement is also interesting.
