I went back in and used both Chrome and Widows and could load the demo. I got to the point of finding the crystal. Is that where the demo ends because I couldn't locate a crystal? Again, I do not have a joystick which would make moving easier, but even using the keyboard buttons was sufficient. Game reminds me of Mario where he looks for/avoids things so that in itself is not unique. However, I would have kept playing your game to see where it took me.
