Your island is buried in trash and the little slobs dropping it are not going to
stop. Drag your cursor to vacuum the mess into the bin and get paid per piece,
then spend it on a wider radius, stronger suction and a bigger bin.

The twist: cleaning pays, so you hire more slobs to make more mess. Four islands
to work through, each filthier and richer than the last - but moving on wipes
everything you built.
