There are quite a few updates:

• I finally updated the demo code (that's hosted on the github.io page) to the cleaned up physics code
• I made the controls system a bit looser - added arrow keys for movement and space for jump
• Fixed a bug for the resize of the level editor
• I added ladders a while back, but I don't think I added it here!

I'm also currently trying to find some people to help me move the game into more of a full game direction, including level designs and story
