Gas Mask pushing-up and BONUS BANDANAS WOAHHHH

re purposes some of my shitey code to add the ability to push up gas masks / other masks over your head

right now it is only for the gas mask, but if people send me sprites for other masks I can get them added in
yes, it stops it from functioning as a gas mask.
