How do you exit the program?
Why doesn't the character move once he faces front-left (towards the bottom left of the screen)?
The rotation controls are very "unresponsive" -- you start dragging, but nothing is happening, then you stop and suddenly things rotate wildly (especially with right click).
No idea what's the difference between left-drag and right-drag -- the explanation isn't clear.
Couldn't finish even the very first "level" (if there's such a thing).
