The idea you wanted to show with this game seems pretty cool, but it still could have used some text for the story telling, since I was a bit confused :D

The music was good, the art was ok, but you could have added a skybox in the background, and there were a few buildings clipping and showing under the road. The gameplay seems good, since the main focus here seems to be on the story. There is a small bug where when you press E to push the boxes, the collision check seems to show up on the screen.

Good luck in the game jam!
