tricky
oh yes, what a good game... this is such a nice idea - interacting with objects without touching them! great idea, made me very curious about the next parts (where the hell are they? i wan't to PLAY them;)))...).
the only thing i didn't like is, that using a object the wrong way leads into a dead end. well, but in this case it's not too bad since the whole game isn't that long...
overall:
very well done - i loved it!
