Skifree.js

This is a work in progress JavaScript port of the popular 1991 PC game Skifree.

I just started work this Christmas 2012 so I've not done a whole lot yet.

Play this right now if you want to (opens a demo page)

Features so far:

• Skiing down a never-ending skislope with randomly-generated trees which do not have transparent backgrounds
• Collision detection with trees - and the appropriate reaction
• Turning left and right
• Stopping
• MONSTAHS! GRAAAAHHH! They even eat you and then run away because they're full
• Distance tracking so you can see how far you've gone you absolute badass
• Speed boost (this was a little-known feature to get away from monsters) using the F key
• MOBILE SUPPORT - This is cool - try loading the the demo page on a mobile device and then use your finger to direct the skier around the pistle. Also try double-tap ;)
• Rainbow jump platforms & jumping - though a couple of improvements could be made
• LocalStorage high-score (thanks, @ddoolin!)
• Custom-sized Hitboxes
• Big trees & crashing into them both whilst skiing and jumping

So, what's left to do?

This is what I'm gonna do, probably in this order. Who the hell knows. There are other features to the original game but I'm not going to add them to the list until I've gotten through this one.

• Rocks
• Snowboarders

Some features which weren't in the original which I'd like to give a go:

• Being a snowboarder instead of a boring old skier
• Tricks, or something?
• Multiplayer (ooooo wouldn't that be fun?!)

F*ck this, let me play the game goddammit

• Open up index.html in Chrome, or maybe even Firefox - I haven't tested it in anything but Chrome and Mobile Safari yet, and I probably won't I'm afraid
• Go.

I like to run Unit tests before I do ANYTHING.

• Right, well first you need to do an npm install
• Run mocha and you should see some beautiful passing tests

This is pretty frickin' sweet but it's clearly not finished. I can totally improve it. Let me improve it, dammit.

• Make a pull request with your awesome additions.
• Maybe raise an issue?
