The Junior Jiffy Game Kit #1 is a safe, easy to use, beginner's introduction to the art and science of creating HTML5 games.
In Game Kit #1 we deliberately limit your choice of level tiles to two -- a cement and brick texture. We do this to encourage focus on spacial development. It is seductive to use texture decoration to hide flaws in fundamental design.
We want to help you learn from the ground up the fundamentals of game level spacial design. Hence, limited texture tiles.
We also limit the number of available entities to bat, teleport, and level spawn point. These give you a good basis set of game elements without letting you get lost in apparent diversity.
Follow the game plan, do your assignments, and you will be blown away by the game development insights you uncover.
This is about you learning -- learning by doing.
