## Overview

Game-canvas is a small native JavaScript canvas game. The player jumps over moving obstacles; collisions trigger a loss and restart delay, while passed obstacles increase the score and the score can affect game speed. The sampled code shows gameplay, drawing, and sprite responsibilities, but not the main loop or input-handler implementation, so those connections are omitted.

Main entry points: [`pedras.js`](https://github.com/gustavosoriano/game-canvas/blob/master/pedras.js) (Obstacles), [`samurai.js`](https://github.com/gustavosoriano/game-canvas/blob/master/samurai.js) (Samurai), [`chao.js`](https://github.com/gustavosoriano/game-canvas/blob/master/chao.js) (Ground), [`sprite.js`](https://github.com/gustavosoriano/game-canvas/blob/master/sprite.js) (Sprite assets)
