Collectibles added 1 1

I have just added collectibles to my game. It was a bit harder than I thought it would be because I'm used to thinking in terms of monolithic engines that handle everything for you.

I… I honestly don't know what to do now. Some feedback right now would be really helpful, and while the with instructions for building is available, I doubt most people will actually do it so I made a test build and published it =>

Playing the game:

1. Download the index.html and main.js files and put them in one folder;
2. Open the index.html file in the browser.
3. Type letters and press enter to cast spells (there's autocomplete). There are currently 5 spells: left, down, up, right (for moving) and a test spell: "kool spell". You can get it by picking up yellow collectibles.

Enjoy!
