Wow, those graphics are cool! I really loved the art style you chose, and the music is fun too, although a bit repetitive. The mechanic of speeding up with soda and slowing down with hamburgers wasn't clear in my mind, but it did make the game a bit more interesting. Despite all that, the game isn't very enjoyable, and I think the way you tackled the jam's theme felt a bit forced (in the sense that you pushed it too hard). After all, what difference would it make if I moved the person holding the box instead of moving the box itself? I'm sorry to say this without offering solutions on how to make the game better. However, I hope you continue developing games because you have room to grow and improve.
