It would be nice to have some response from the menu items. As of now I didn't know if the game worked or was froozen when I loaded into the main menu.

I would have liked to see thing only carry one item idea explored more. As of now- You don't need to manage and juggle between items. You just have to walk in a straight linear path to beat each level- never having to think about the one item at a time rule.

Would have been interesting to see a level where you first need to find a way to the exit and then a way to carry the key to the door.  And during that having to switch back and forth between differnt items and the key, juggling them back and forth to reach the Door.
