I agree with everything that was written good here about this game, I spent, it seems, more than an hour in it and got to the 7th place. The music, the sounds, and the idea are all very well done. But still, I'll write about some of the flaws that I found while I was playing.
1) Many people have written about physics, so I don't see the point in staying too long, it just happens to be a pity for a car or a house that is stuck in the ground.
2) In the leaderboard, the "back" or "restart" button closes the nickname of one of the participants. It seems to be a minus, but at the same time it worked for me as an additional motivator not to be closed by the button.
3) Sometimes, when I put up the building exactly at the moment when the time was running out, my score became just 8 or something like that instead of 148. Perhaps the last size of the delivered object was taken into account, I'm not sure.
But for all that, I really really liked it. Thank you for creating this game.
