Before you write a single line of JavaScript, a browser game needs a plan. Game design fundamentals are about answering a handful of deceptively simple questions: What is the player trying to do? What rules govern success and failure? What objects exist in the world, and how do they relate to one another? How does the player act on the game, and what does the game show back? Writing these answers down — in a short design document or a rough sketch — turns a vague idea into something you can actually build in a few weeks.
In this course, design discipline matters mostly because of scope. A browser game built on Canvas with a single game loop can support a surprising amount of play, but only if the entity list stays small, the rules stay clear, and the win/loss conditions are decidable in code. Deciding early that you have a player, a set of obstacles, a score, and two end states makes the later work of looping, rendering, input handling, and collision detection far more straightforward. Changing your mind about the core objective halfway through does the opposite.
The videos below come from game designers rather than web programmers, so treat them as sources of design thinking, not implementation detail. As you watch, listen for how designers talk about a core mechanic, how rules create interesting decisions, and how constraints improve rather than limit a project. Then translate what you hear into your own one-page design: objective, rules, entity list, interaction model, and a sketch of the screen.
