Ok, so the author thought it's a great idea to embed a little mini-game onto the page - in case two squares shot by the things in each bottom corner ever collide, your mouse cursor vanishes. Brilliant - tab closed.
PS. fix the origin of the projectile shooters - right now they are shooting from the "side" and it looks sloppy.
Oh so that's why my cursor randomly vanished. I ended up just putting it in the middle right at the bottom so the little squares wouldn't get in the way of me trying to read
