It's interesting that you say that, because we have been thinking we could make games like this and market it towards schools/teachers to teach the meaning of words in a fun way.
The post-jam version of the game will include better tactile feedback for the puzzle as well as a hint that shows where some of the puzzle pieces go, making it easier to get through. If you want me to make an altered version with a slightly less violent defeat of the wolf, I can do that quite easily by removing the wolf laying there dead. So it would just be the tired rabbit left.
