Canvas game engine

This project has been discontinued, there are a lot of good canvas engines out there, i'd rather work on something more exotic. https://github.com/MarcoWorms/asciiD

WormyJs

HTML5 pure JS + canvas game engine

Latest release - https://jsfiddle.net/1c57vhs1/18/

Hi there! I'd like to talk about this engine's purpose.
I'm an amateur gamedev who likes to fastly protoype a game mechanic just to see how it's like. I'm writing this to be a "game prototyping engine", my goal here is to make a fast approach to common basic gamedev needs like "draw a colored square(or circle) instead of an sprite" or "give me fast basic collision". I came from ruby to js and this idea was inspired by Gosu, Phaser and Construct2.
Any feedback is welcome :)

Alpha notes:

GameObject properties: x, y, width, height, shape
GameObject methods: centerX, centerY, r, distanceTo, boundingBox, isColliding, draw

*both draw() and isColliding() will adjust itself accordingly to it's shape

*spherical GameObjects will be drawn based on centerX and centerY of it's boundingBox

How to use the Engine:

• You should override: initialize(), update() and draw()
• Initialize your GameObjects in "initialize()"
• "update()" runs 60 times/s, use deltaTime modifier for framerate independency. Use this for your game logic.
• "draw()" is called right after update. Use this for drawing your GameObjects
• Use "this.drawText()" to draw text
• this.keysDown contains user input

*both background and default drawing colors can be set at "clearCanvas()" method on the Engine object.
