Like the game, this is super creative and enjoyable.
But the box pushing is way to wonky, slides around too often. I know it's difficult and I don't want to seem like I want a EZ MODE but it's super annoying to have it be push back to the start when I only have 3 seconds left.
Ice and Snow doesn't feel different enough. Make sense for it to slide a lot on ice but it's seems odd that it also slides a lot in snow (Maybe a suggestion but making it slower and more manageable in snow but faster and uncontrollable on ice would be a neat idea) but overall I like it.
Keep it up
