Prototype – Dawn of the Dust Bunny
You are a dust bunny and are attempting to grow big enough to escape. This will incorporate both two button & growing. You are able to become DUST DEVIL and rise up, or PAUSE in place. Mabel is always moving and she will have a duster of some sort. As you roll over dust, you will pick them up and grow, eventually being big enough to escape the room. 
I need to get some sleep, but feel really good about getting stuff accomplished over the weekend to clear it up a bit.
