The PDF had a typo, but it was otherwise great to read some backstory.
The art demo worked well, but it was annoying to chase it to see. For the future, a walk/stop feature would be nice.. as would a ledge to look down.

I played with the keyboard to eventually learn F11 will fullscreen. That instruction would be good to have at the opening screen.
