What I loved most about this game is the way it teaches player. It doesn't tell you anything, yet it highly encourages you to experiment. With the right tools placed at interesting locations to give you strong temptations. This natural curiosity allows the player to figure the game out for themselves. Putting a knife on a ducks head was never more natural.
I love the creative freedom in this game. And the only thing that would enhance the experience in my opinion is to add extra assets/objects.
I would highly, very highly encourage you to finish this game. Because I do think this might be the next Scribblenauts.
