On default configuration and using a controller, it would walk forward when left stick is not used. Needs to have "--y-tilt-offset=24" added to options to work properly with controller. After adding it, it controls fine.
Scale hack is slightly broken: motion blur effect when katamari grows in size looks wrong, image of katamari in the King's hand after completing a level looks wrong.
Alpha blending is broken for some reason, making various things look ugly and obscuring the screen for a few seconds when the katamari increases in size.
