OMFW!
You fucking used some of Thirstyforchicken's (Jeffery Liu's) 'Mask' in that!
I dunno if you might get away with it though. Looking at the date this was put on newgrounds it looks like you have. But of course you have added your own stuff, i suppose. At least it's not copied straight off. But 'Mask' has been my favourite flash for a long while and might always stay that way.
