Block Push Plot

It plays like a classic push puzzle with one nasty twist: open pits. Walk into a house-block to shove it along, line every block up on its plot, and mind your footing the whole way, because a block dropped in a pit costs you a life and a worker who falls in ends the level on the spot.
Heavy blocks need a proper run-up before they will move at all, the plots get crueler as the risk climbs, and you can undo and replan any time a level turns into a trap. Forty sites, no clock, no rush.
