Good job on your first game. I would have liked it a bit better if the main character was somewhat more proportionate to the environment.
The game mechanics were a bit unclear to me, aside from the box pushing. But even that I struggled at first to recognize what can or cannot be pushed. In the lava levels it seems there are additional mechanics where the box "suck"(?) the brown dirt(?) in but I'm not sure what triggers it or what's the supposed mechanics is. Would have loved some more tutorials/explanation.
