I'm new to the Kongregate APIs, I thought the statistics would work for highscores... Guess I was wrong.
There is another version with highscores (including facebook integration)

I will get around to fixing this version.
Cheers for the comments! Sorry about the bugs. Thought I'd got on top of that problem.
Anyway, cheers everyone for the positive responses. I promise to make my next game a bit more interesting.
