[Credit to Windbreaker for the title.] "Until they've searched thoroughly, one can never be clean." In this scenario, you get to spend a bunch of time cleaning up a space of its filth balls with your trusty Yucatan Suckaman™ vacuum cleaner. But watch where you step, and be sure to empty the bag often so the vacuum cleaner doesn't explode!
Today I added two new maps: "Testing Against Distance and Polarity" and "Funnelpath Iteration Overcoming". These can be downloaded individually or with other maps or the scenario itself at the provided link.
