Interesting idea, I like it.
I managed to find the first powerup that is rope. What kept me from sticking with the game is enough repetitive background and little action, mostly walking through chain of similarly looking rooms. Also I miss sounds very much in a game like this. I tried and managed to kill one of the bad guys, but only because he didn't hit me back. Likely later in the game I should receive some weapon. I wish I find further way to overcome big boys with guns but it's hard to navigate in such monotoneous locations without a map and having to walk inside each room to discover where I can go further from it.
