So far I love the game, and this is the only thing keeping me from a 5-star rating for you:
I'm having a problem with the room "005" too, both player and AI's freeze but music keeps playing. For me it happens after I close out the bubble that says the door/whatever is locked. I love the game so far but can never get past that point.
I tried using Play, hoped that would get me out of it, but when it went to the next level the player char is spastic switching between "without the suit", "with the suit", and "dead in the suit"
I run Firefox on Win7 and keep Firefox and my Flash player up to date.
I'm not sure what details are important so I included everything I could.
