Congratulations on your first jam entry! The pushing mechanic is a neat idea! As others have said, the time limit was a bit short. One suggestion I would make for your next jam is to look into some of the built-in physics features of Unity (or whatever game engine you use next time). There were some issues with the red can getting stuck or the blue can going through the red can, which I think could be fixed by using Unity’s built-in rigidbodies and colliders. Great work and hope you keep making games!
