10.05.2016: Added some new stuff and generally tweaked a lot of things. Now the game can be run without installing, supports keeping track of your progress, and more! EDIT: Fixed the bizarre score tracking bug.
It's obviously nothing groundbreaking, but I did my best to make it work as good as possible, and to give it some decent graphics. Personally, I feel pretty proud of it, even if there's most likely thousands of games like this out there.
Too bad GameMaker doesn't support exporting games as SWF, otherwise I would have made it possible to just play the game in this very window.
