I just figured out how to use stor! what you do is you set a ctype for it lets say dust and then you can put that on the stor and it should absorb it but it won't absorb if it has to much that is why it keeps on piling up! then when you spark it with pscn it will get rid of the parts that are brighter around the edges (if forgot to mension when it absorbs a paricle it changes colour to a brighter colour) when you spark the pscn it gets rid of the outer edge part with about one to two pixels.
suggestion: I think that cracker or someone should fix it so that when you spark it with pscn it gets rid of all its holdings. (if my suggestion sounds harsh I didn't mean for it to be, I'm only making a statment).

after the most recent update the store was fixed.
