If you know about #js13kgames contest you might be interested in my small game created for it. I called it Cannon Defense, but the sole purpose of creating it was to learn in practice how to create a game. You can say that it looks ugly, or is small, but for me it was great co create it. My submission is not yet online so if you want, play it at: http://krzychukula.github.io/js13k/ Code is on github: https://github.com/krzychukula/js13k What I have learned: User constructor and prototype inheritance for game objects. function Bullet(x, y){ this.x = x; this.y = y; } Bullet.prototype.draw = function(ctx){ ctx.drawRect(x, y, 10, 10); } It will be more memory efficient. Do not use translations to move objects For me it was hard to manage bullets flying at various angles and the first idea was to translate all bullets to cannon position, then add some offset variable and just move bullet on one X or Y angle using offset. It worked :) Until I had to check
