You do! Eventually you can suck up everything. Level 2 has you sucking up cars and houses :)

That’s exactly it. At first you are sucking up lint and cigarette butts, level 2 you can suck up glasses and cans, and so on. Eventually you have to move a bookshelf to find the exit.
Sadly I set the difficulty too high and some people are struggling to reach the exit. After the jam I plan to tweak the difficulty and add a third level.
