Pretty fun, though I feel like I've done most challenges by trial and error rather than puzzling out what I need to do. I found it difficult to know ahead of time what my move will do. I think it would also help to show cats being confused when they can't decide on a move, but that might be just me being a brainlet and not remembering the rules.
Also on Challenge #7, it's possible to complete with 1 House left. Not really an issue, games like this can have multiple solutions
