Hellooo, neat game you have there. The idea is easy to grasp, after I finished the level and died into the spikes, I understood that you were supposed to carry the box to the finish :) After that is was straight forward, finishing the levels (my personal favourite were the conveyor belts). Simple, compact, rounded up. There are some Quality of Live changes that could have been made to improve the game flow, for example the box could have become a sphere since I had some problem pushing it over edges sometimes. For some reason the platforms also felt like they were immensely slowing down towards their final position, making it even hard pushing boxes over. And sometimes there were irriversable moves which made you start all over again, which didn't quite feel that nice. But all that is just bashing on a solid gameplay with multiple levels. As such I can only say good job, keep up the good work!
