IMPORTANT:
I just found a bug. Before you start using any of the direction keys to control the game, you need to click anywhere in the game. I'll try and fix it as soon as possible.
To start off with, this was just an experimental thing to try out some new methods. I was quite pleased with the finished result, and I just wanted to know what you guys think, so here it is...
PS:
Please post any bugs and comments, I'll try to get back to you as soon as possible.
