A very good start
I like your art but the game is buggy for me so let me break it down for debugging:
I can't 'enter security door' or 'talk to nurse'(yes even when injured) and thats all the bugs.
Flaws:Escalator labeled elevator....same difference I guess. The terrorist fight is too easy and I can't use the cash or get into the janitors closet. Minor flaws are that the character appears in center of screen instead of edge during room changes, and one that is probably only part your plan to expand the beta is I can walk off screen on the second floor.
BTW ref'ring to 'Hawai" dude I didn't know crack could be smoked in a spliff,I gotta try that sometime ;)
