It's totally mouse driven, but you need to click on the particular things that you want to interact with, you can't move around freely. So you click on the kettle to make tea, the freezer to thaw meat, Ed to hang out with him, and Elizabeth to hang out with her. The tea and meat become clickable when they are ready. I had hoped to get some more obvious indicators of what was interactive in, but ran out of time!
Thanks for checking it out anyway!
