Great implementation of the jam focus. All applications of the stick are both useful and easy to use. The day/night mechanic works well, making it very difficult to stay up too late. The graphics and sound work well together to create a suitable atmosphere.
The circle of light around the character at night should be a little broader, I think. When using the stick as a compass, I can't even see the end of the stick.
The toolbar at the bottom looks somewhat squished.
The hero stands out against the background, of course, but would look more interesting with a little bit of color.
