There are slowly-rotating objects that it seems like I should be able to pick up or something? But I can't. I assume this is related to the fact that I have no idea how to beat the first level (I defeated all enemies and went to the princess). Not sure if this is supposed to happen, but I also can walk through the cage around her and some other objects (castle-looking thing).
My mouse didn't seem to lock to the game window so I could only turn so far before my mouse hit the edge of the screen. Other than that it is a cool game to play around with!
Looks like fun. (FWIW, seems to work in Firefox on OSX.)<p>Unfortunately, using WASD for movement is very uncomfortable for me, because I am left-handed and use the mouse with my left hand.
