Brain teasers gone numeric

'Priscilla Gone Missing,' an escape-adventure-flash game like the famous 'Crimson Room' brain teaser mystery, utilizes a wordnumber for one of the steps. Translate a string of four letters that appears on the ground into the corresponding numbers on an on-screen keypad and 'you're in' [the elevator, that is].
