BatMario, I have implemented the fullscreen mode (press F11) as requested. CTRL+X to quit. There is also a worldwide high score for those who beat the game! Enjoy
BatMario, this night I'm going to upload a newer version again, since in yours there is a big bug later in the game. As you may have noticed, now there is a official Leaderboard.
The newer version sports a new renderer with fluid subpixel scrolling. I strongly suggest downloading it and trashing the old version! I'm waiting for you to get to the million! :D
