I've been playing this game for a few days now.
It's crazy. As a bungeeing yard gnome - see, it was made for me- you have to fend off elves and santas arriving in sleighs, with a brick. Plus you can call in air strikes. Oooh! Ooooh! And you can create a brickopacolypse by exploding all the bricks off your moving building. Just don't let those damn elves get to your chimney or it's all over.
