I have been playing this one level (Maize) for days now and still have not beat it...but I have come excruciatingly close (all but one block placed)...any tips, hints or suggestions?
I'm not sure how I did it, but you gotta use the squares wisely as bumpers to the circles. You might also need to "park" some objects temporarily in the middle area.
*waits for power of posting to work*
EDIT: 10 minutes later, it did. :D
