nice visual style, nice pacing. maybe the main hub world could spawn you outside the level you just came from, so you don't have to walk as far to get to the next level. maybe since boxes are heavier than the player, they should be harder to push.
I agree that the boxes should have been harder to push, but since I wasn't using rigidbody for movement I haven't had any idea on how to resolve that. Thank you for your feedback!
